When I reformatted and reinstalled all of Windows XP (last year or so), I feel I might have screwed up and somehow kept the other version on it. The reason I think this is because now, whenever I start up, it comes up with a black screen that asks which operating system I want to run. The options are 'Microsoft Windows XP Professional,' and "Microsoft Windows.'
Because of this, it's been running slower then normal.
Do you remember to actually format the hard drive at some point? Also do you remember if any of the programs and documents from the former installation got transferred in the new one?
I've seen cases where the hard drive was formatted but because of partitioning configuration the setup program belived that there are two operating systems available that especially on Dells that have a bootable diagnostics partition.
If there were no files that remained after formattting and if you remember clearly getting through a formatting process you can get rid of that annoying message by doing the following process:
1. Click Start, choose Run and execute msconfig. The System COnfiguration Utility will pop-up
2. Click Boot.ini on the top and click Check all boot paths.
3. Click ok to any messages that come up and then restart the computer.
Hey i think i run two windows on my computer .. because first i had vista and then i installed windows 7 ... so now that i check my hard drive 150GB of it is gone and i think its because of the files (eg.movie,games..etc )that i had in my windows vista.. so can anyone please tell me how to go back and use my vista cuz i had some important files there. thanks
Aw, heck.. the detail you don't give. Uninstalling an OS should NOT remove any of your other [data] files. Installing another one afterward with a quick format will likely overwrite them. It depends.... if they exist on the hdd but are lost then it is possible to sometimes recover some of them. Reinstalling Vista on the same partition will just compound your problem. Anything that Vista could see should be visible to W7, other stuff may need special recovery tools. Ask if you need help with that.
