Hi,
I am fresh Ubutu user and an avarage computer literate.
Installed Ubuntu 10.10 on XP Service pack 2, opted dual boot.
After few days of work I wanted to boot windows but could not.
Followed some related posts in the forum. The following is the boot info script.

=======Devices which don't seem to have a corresponding hard drive==============
sdb I followed chkdsk advise i got in the forum.
I tried "chkdsk drive /p /r " for couple of times (till there are no errors) and restarted. But the problem remains same.
How to resolve this?
Thanks and regards,

=======Devices which don't seem to have a corresponding hard drive==============
sdb I followed chkdsk advise i got in the forum.
I tried "chkdsk drive /p /r " for couple of times (till there are no errors) and restarted. But the problem remains same.
How to resolve this?
Thanks and regards,
Pavan
