Windows & DOS: Issues & Discussions

I have a home pc with dual boot (Grub) with Red Hat as one OS, and Win XP as second OS.
Recently, I removed RedHat with Solaris, but Solaris removed Grub and marked win xp C: partition as logical volume.
I removed Solaris with redHad after that, and I have Grub again... but second OS (win xp) is not working...

what should I do?
someone adviced me to use fixmbr, but i have only one shot to fix it

We need more detail. Please print your partition layout as reported by 'fdisk -l' as well as your grub.conf or grub.lst file.

when i start windows repair console, i could use tools like map wich says:

e: xxx mb \Device\Harddisk0\Partition1
c: ntfs xxx mb \Device\Harddisk0\Partition2
f: xxxx mb \Device\Harddisk0\Partition3
? xxx mb \Device\Harddisk0\Partition4
d: \Device\cdrom0

if I edit grub, there is 2 options:
rootnoverifiy (hd0, 4)
chainloader +1

second one is for windows, and it's not working...

how could I start fdisk?
