sudo dd if=./linuxmint-17.1-cinnamon-64bit.iso of=/dev/sdd bs=1M

You copied a file (image) to a device, not a partition - everything under the iso is hosed, the partition table has been rewritten. Why do they nick dd the data destroyer? beats me...
Anyway.... Linux conforms to the ntfs spec, so the backup table will be overwritten, also. What will remain are the old sector boundaries that have not actually been overwritten (by your iso or other) for all old partitions - TestDisk can find those using its sector search (Deeper Search).
You must recognise the valid from all that it finds, and write them to the table. Of course, the new partition sector will be the first valid one. Your searches can be quicker if all your partitions were written to cylinder boundaries (XP spec); if not necessarily so (Vista, W7 spec), then the search is quite slow.
Each boundary sector (there are beginning and end sectors) contains a table with beginning and end info for that partition, and the MFT location. You need those MFTs - without them, files are simply lost. Testdisk can read file tables, but not rebuild them. So if you choose an incorrect boundary then TD will likely not find that partition's FT (you test by checking file lists, contents).
When satisfied, you write the table. Not correct? Nothing more is lost, but time - you do it all again.
As for your OS, 1.4GB is a lot to lose; there is an excellent possibility that your FT ...

These often come in on some plugin or extension, addon that you have installed, perhaps unknowingly with some other software or webpage you visited. You can check your plugins, uninstall and delete those you don't need or use, or you can run AdwCleaner by Xplode (free). Read the simple instructions to remove adwares.
Say how you get on with it, and if your problem persists.

I think winlogon is trying to load, but registry reads are faulting. And that's the end of it.
Mucaa, restart your system and immediately press F8 several times to get into the Windows Advanced Options screen (black, with white print). Choose Safe Mode - as it prepares to load you will be presented with the option of System Restore. Enter that, and try a recent restore point.

Yes, latest Win to Flash is loaded.
So you get around it. You keep only the one language (409 is English), Logs, Options, EULA, .ico, and the exe.
And then no problems with adwares, add-ons.
Of course, there is also Rufus. I think it might even be better. Faster, anyway. It's what I use.

W10. I could worry that it is going to be regarded as a service. You know, something like electricity, gas, water, for which you pay a monthly bill. M$ would like that, is probably moving to it... W10 is a free upgrade from W7 & W8, but...wait for it..."W10 will be free for the first 12 months".
But I won't worry, actually, cos am sticking with XP.
Suck on that M$.

Urg. Could be anything. Dry solder joints are more common than you would like to believe. A tiny trace of corrosion around low power joints, hydrated salts remaining from cheap flux, dodgy connectors, the mb monitor chip, the ps's controller chips. Tap those chips briskly with a pen - they sometimes go "microphonic", meaning an internal pin out connection or silicon junction is intermittent.
I'd check if the PS was receiving a PSGood signal from the mb, and if so, was generating all requisite voltages. And if so, then I would sigh and consign the thing to a bin. Power supplies I can do; I cannot work with components that I can barely see. Others may be able to. There are in use components that are sub-millimetric now... :(. Interestingly, they are more reliable than their larger kin (it's a heat thing), but impossible to work with manually.

Everything that is legal you will find here:

I don't know from your post whether you are attempting to unlock someone's PW, or to unlock from a provider. Certainly they will guide you to unlocking from a provider. But then, often too, will the provider if you pay a fee or a certain time has elapsed. In PNG it is possible that your provider is TLS? - in which case, the last advice does apply. Check xda for your model, visit the forums.
Okay, from your topic header, it's a password unlocking you seek... Mobile phones are computers - you can ...k, I'll stop here.

"One caveat is that not all of Youtube's contributors are experts."
That sounds awfully sweeping.... there's a utube of a russian showing how to stop the clingfilm roll leaping out of the box when you pull the film, and well, he's basically nailed it. He demonstrates how you should push in the lock-in tabs on the ends of the box. utube is truly a necessity of life.
w3schools cover html, for example, quite comprehensively but you really have to practice what they preach, and not just read. Learning is about understanding and repetition. Read a bit, code and run a lot. Code anything. I found the best way was to code a project that I was interested in, and learn as I went, redo the clumsy bits, and polish everything. Coding is like electronic design - there is always another dozen ways to achieve the end.

I'm reading this as someone who is annoyed by people wearing and using bluetooth gear. Even strangers. Company risks a bricking. By "certified nerds" I know you mean top-hole nerds who have been certified as unfit to be in public places. People who really know me turn off their mobile phones when spending time with me. Okay, I'm so old fashioned. But I know and understand the hierarchy of importance, and the concept of politeness.
Glass was just a wrong turn in the employment of technology. I'm thinking smart watches will recognised as such, too, one day.

I wrote "So all is good, Lx IS on 4, Swap on 5." I did mean 4th physical and 5th physical, not the MBR order.
I'm moderately sure that that error msg about ntoskrnl missing comes from winload.exe, the pgm that loads the windows kernal and then hands to it. I think with W7 it goes bootmgr reads config data, loads winload, winload loads the kernal and drivers. I rather think that Grub has taken over the W7 boot manager's job by installing itself there, and messing up boot. But then you can get to the W7 boot manager via a different Grub link, and that works. So... I'm confused, but since your Active partition is the Dell Recovery, I guess Grub is there, and possibly the bad W7 link points to the wrong partition or more likely is just plain bad, so reinstall/fix Grub (this lil duck cannot do that), and the good link points to the W7 partition and its boot manager (bootmgr used is in the volume boot record of the selected partition). A normal W7 boot would involve the Active partition and its volume boot record. Ok, I admit it, I'm lost, and I find the Grub config data too arcane to get interested in.
Can you live with it? Else it's off to the Linux forum with you.

Could be any of three or four things...
-dust-laden heatsinks - brush and vacuum/blow clean
-driver software corrupted - reload it.
-faulty RAM - test it with Memtest86+
-faulty video card - stress test it with Furmark
I'd probably do those things in that order. Putting the worse news toward last...

Crazy. From your wording it almost sounds like you want to somehow have Minecraft access the RAM in the desktop from the laptop. Maybe in Startrek, but not in any world I know of.
If you wish to physically swap RAM sticks, then no to that also. The two RAM systems are physically and electrically incompatible.

Certainly, muhammad, 4 GB of RAM will make a very noticeable difference, even with your current OS. But 32bit OSes cannot use quite all of 4GB. 64bit Windows 7 at least, makes better use of available memory because of an improved memory manager, plus is capable of using all of that 4GB compared with 32bit W7.
W8.1... I don't know how efficient its memory management is. Of course, there are still softwares that are not available in 64 bit, but 64 bit Windows 7 or 8 will run them as 32 bit. So consider a 64bit OS; your current E4500 is capable of running it.

Oh. Didn't spot your reply. Um... the actual records in your partition structure are simply out of order, which is of no real significance because it is just a list which gets referenced by entry number or searched (eg. for the Active marking), but it plays merry with humans. You can reorder them, but puters don't much mind. TestDisk lists (in that screen) and Windows Disk Mgmnt depicts the partitions as it finds them in the MBR, Lx seems to order them, which is why I thought your Swap was huge (went by the size in Disk Mgmt), and also that boot might be Ptn5. Just as an example, (and one of a perfect structure) I show you a pic of mine:
Boot, then 2 more Primaries, followed by an Extended partition - you can see that the first record of it envelops ALL of the Logical drives. Following Extended partitions envelop each associated Logical drive, which start on the next sector. My partitions all end on cylinder boundaries cos I'm using XP, but W7 partition boundaries are not fixed so. Back to your table...
At the end of your third Primary there is a small gap... no biggie. First Extended (4) points to the following logical partition in the chain (the Swap), while its own (the L Linux) starts on the next sector (again, first E is shown covering the whole of logical drives, but that is not significant, MBR-wise).
So all is good, Lx IS on 4, Swap ...

Curious, here. What device is it actually booting on.. dev/sda? I don't think it is sda4....
If you don't mind, it'd be good if you got hold of TestDisk by CGSecurity, and ran it.
Start it > No log > Proceed on disk > Intel > Analyse ... and take a shot of that first screen with the partitions (it's a snap of your MBR).
Post it? (if you go past that screen it is reading partition boundaries from the disk, and that that can show a mishmash cos it picks em all up, even non-overwritten oldies). Not interested in that, yet. Just curious about missing Ptn3.

That missing partition 3 puzzles me. Let's ignore it for the moment.
P0 : 0xde is Dell Utility, so SteveDotNet may well have been right about it, above, after all.
P1,2 : 0x07 are NTFS for W7 (see that your Recovery ptn is set Active, is System? It contains your boot files for W7. Urg.)
P4 : 0x82 is Linux Swap. Pretty huge for a swap partition. Really huge. A dead loss of space.
P5 : 0x83 is Linux, type ext2. So I mixed those last two up in my mind... :)
Anyway...
Note that the command to check a directory terminates with a "/", so:
ls (hd0,4)/ -the "/" makes it a pathname, actually the root directory here.
The tab in ls (hd0, ) just does an auto-complete, or blank query, if you like.
root (hd0,4) might have worked. Or root (hd0,5) ... that missing ptn might or might not need accounting for. But...
ls -will list the partitions.
rootTAB -will find the linux boot ptns. Then root it thus:
root (hd0,?) - get the ? from the root cmd output above. Then:
kernelTAB -will give you the kernel name to use for kernel and initrd cmds.
I could get you to run another software under windows to discover what that missing Ptn 3 is...
That swap ptn.... should be only 2 or 4GB, really. And boot files in the Recovery partition is a bit... untidy. See how we go booting Linux first.

Hi. You would have to check your memory usage figure in Task Manager under Performance tab - the Available figure. This refers to the amount of free RAM available for processes and their data files. The memory manager will not allow this to drop too low - it always keeps a variable figure in reserve. Solution is to install more RAM.
Or is this a Virtual Memory Too Low warning? If so, you can easily increase the size of your page file to cope with the load - guides are all over the web.
The thing about email clients is this... all emails of a folder are kept in one continuous file. If you are using Inbox and have hundreds of MBs of emails in it ( I know of such people...), they all are loaded into memory. An instance of a spreadsheet software like Excel may take 80 or 100 MB of memory, plus whatever the size of your particular file... some are huge. Add that file to your email client and memory demand increases. My advice is to run your eye over the folders in your email client, and DELETE the cute kitten and Walmart presentations. There will be others - trust me on this... someone's probably pressing Send as your read this.
Oh, and use the Compact all Folders feature - it actually physically deletes the deleted files from all those folders, and rewrites the folders' files. Otherwise they remain until doomsday, and bloat. Unless you do ...

" I would only do a BACKUP every 2-3 months"
EEK!!
My sys does one (incremental) every day if it's running. And I re-image my system drive every couple of months, and disconnect and remove the image disk. Why? Because I KNOW it takes at least a full day of hard work to get a new installation set up completely. No thieves, no viruses or kiddies where you live? And disks do die.
Seriously, SyncBack (or similar) is the go. Free, can be scheduled, and will do automatic, periodic, background backups of work if you so wish. Has the power never gone off at your place?
If you've got a good BU software, you rarely need to touch it. Another thing, there are a LOT of posts on forums about file recovery, there are businesses which do little else, and all because people don't do timely backups.

Anyway, from the tenor of your post I'm guessing that you do not have a backup disk drive right now. Not just a partition on your main hdd... that just does not cut it as backup at all. A separate hdd for backups and warehousing of stuff is safer. So use it for that. You could even put your main page file on it as an outer (first) partition to speed your sys a little, with still a small one on your main hdd.
If you don't put a page file on it, but just use it for backups and warehousing then set it in power options to shut down after, say, 10 minutes, because you will likely set your backup software to run just once daily. Less wear and tear on a seldom used drive. With ten minutes, if you are doing incremental backups every 5 or so minutes on some important file as you use it, it will stay on for the duration.

Jim, that's a Devices by Type view of DevMgr. Here is a view of my sys in Devices by Connection - you can see that rip-off Cruzer plugged into USB 2.0 (the Enhanced Controller). If I showed you a pic taken of SisoftSandra's display you would see all 6 ports of the Enhanced Controller's root hub with the UFD plugged into one of them.
Then, in the expanded Universal Controller you see my Logitech kbd n mouse running as USB 1.1.
Way it goes: each of the 2 Enhanced Controllers has 6 ports in their respective root hubs. For fallback to USB 1.1 there are 6 Universal Controllers, each with 2 ports in their root hubs. So 12 virtual ports of each type. Of the available 12 USB 2.0 ports in the two hubs I have only 8 physical ports.
The Enhanced Controller of a hub in use does the management - if a device is not capable of USB 2.0 it hands it off to another core in the chip, the Universal Controller.
