So on my dad's laptop I think I screwed up the boot.ini This is because it has vista installed (I hope it still has), and it want's to boot up XP. Through the XP's recovery console I tried to rebuilt it (boot.ini) but it want's the admin password (To log on to C:\WINDOWS). I'm sure I know the pass because another pc has the same pass, and that worked. So I found on the internet that the windows 2000 recovery console didn't asked for the pass. I tried that one, figured out it didn't had bootcfg, googled, tried "fixboot C"or something in that direction, "J" (I first tried Y, but then I figured out I had the dutch version and it wanted J instead of Y), "enter" it said it finished. I restarted the laptop, still wants to boot up XP. So I was thinking, is it possible to boot up a OS (Ubuntu, linux?) from an USB stick and then look if it still had vista installed on C: and if it has, edit the boot.ini, but if it doesn't, backup and install XP? OR, is it possible to install windows XP OVER windows vista and still have all the files on C:\? Thanks in advance.
