Hello,

I am a newbie poster with a laptop question. I have a Dell Latitude laptop that won't boot to Windows (only to the BIOS screen). What steps do I need to take to troubleshoot this problem and then fix it?

Thanks,
Rod

When a Dell Latitude only reaches the BIOS screen instead of loading Windows, that is a symptom rather than a diagnosis. Given 's note about memory testing and 's question about what changed just before the failure, the following adds practical diagnostics and data-rescue options that haven't been suggested yet.

Run Dell's pre-boot hardware diagnostics from the one-time boot menu (F12 on most models) to isolate controller, memory and drive-level errors. Note any LED blink or beep patterns and listen for unusual drive noises (clicking/grinding). If the drive is suspected, remove it and connect to another computer with a USB-SATA adapter or enclosure to check file access before doing any destructive repairs.

Boot from a Linux Live USB (e.g., Ubuntu) to inspect the disk without writing to it. Use the Disks utility or smartctl (smartmontools) to read S.M.A.R.T. attributes and run a short self-test:

sudo smartctl -a /dev/sda
sudo smartctl -t short /dev/sda

If the drive is flaky, image it first with GNU ddrescue to preserve recoverable data:

ddrescue -f -n /dev/sda /path/to/imagefile /path/to/logfile

If the drive appears healthy but Windows still won't boot, repair the boot structures from the Windows Recovery Environment (commands below apply to Vista/7/8/10):

bootrec /fixmbr
bootrec /fixboot
bootrec /rebuildbcd

Additional notes: reseat drive and memory connectors, try a known-good drive to isolate the HDD, check for recent BIOS/firmware updates that may have changed SATA mode, and avoid unnecessary writes to a failing disk. For Dell diagnostics and downloads, see Dell Support; for SMART tools and imaging utilities see smartmontools and GNU ddrescue; for creating a Live USB see Ubuntu Desktop. If data is critical and imaging fails, consider a professional data recovery service.

Noticed this post hasn't seen any answers yet, so lets take it systematcally. All of this is based on you having already swapped memory modules around and run with only one at a time to test if either of them were bad and causing lockups.

1) Enter BIOS and see if BIOS sees the HD, if not then you most likely have a bad HD and need to purchase a new one adn do a clean install.

2) If HD is good in BIOS and optical drive is recognized insert recovery disk into optical drive and change boot order then save and exit rebooting from recovery disk (or recovery partition if the HD still gives you that option which I am assuming it hasn't.

3) Assuming you need no data from current HD as part of recovery / reinstall reformat HD (long format) and reinstall OS. If you have a problem during this process it is likely that your HD has problems with the platters or read head, time to get a new hard drive and do a clean install.
