View Full Version : [ubuntu] Wubi/Ubuntu works, but Windows XP stopped working

Have been happily (well, usually) using ubuntu with wubi for prob more than a year now.
However, a couple months ago, the bootup for Windows XP stopped working. When the computer starts, if I choose ubuntu everything works fine, but if I choose Windows it just loops around endlessly back to the windows/ubuntu choice screen, and never makes it into Windows.

This is on a Dell Inspiron 700m laptop. It's funny that the wubi/Ubuntu has still worked fine for a long time even without it's "host" Windows being able to open.

BTW, I don't have any Windows discs and I think this computer might not even come with or need them.

I'm wondering
1) what went wrong with my Windows, and
2) how to fix it so I can get back into Windows, and
3) if I do fix Windows, such as by a "system restore" or somesuch, will it wipe out my current ubuntu?

Please post the results of the boot info script so we can diagnose the situation.

There is a link at the bottom of my post with instructions.

Thanks for reply, Rubi1200: I hope I've done what you asked here:

Not sure what is going on here, but I will ask some other members to take a look and offer their perspectives.

Thanks for hanging in there.

I also do not see anything wrong. Script is showing boot sector as ok, but it could have internal issues as it just check start & end. Windows boot files look ok (or else you would not be able to boot into wubi).

Have you run chkdsk? I do not think that should cause issues with wubi as Windows needs chkdsk like Linux needs fsck periodically.

I can't see anything wrong either. If you are considering restoring windows then it's a good idea to back up all your data, including the wubi install (the C:\ubuntu directory assuming you installed on C: )

When you select Windows next, hit the F8 key repeatedly (or try this when the machine first boots up) and see if it gives you an extended windows boot menu that offers to boot in safe mode, command prompt etc.
