Good day for all!

I had Windows XP on my SATA HDD (I have only one HDD).
Bootloader (ntldr) was on the first primary active partition
/Windows was on the logical partition
All was working fine.

Then I have copied ntldr, ntdetect.com and boot.ini from first partition to logical partition with Windows, then converted logical partition with /Windows to primary and made it active.
After this I formatted first partition and installed Ubuntu Linux with grub on it.

So, now I have:

Device Boot Start End Blocks Id System
/dev/sda1 1783 1913 1052257+ 82 Linux swap / Solaris
/dev/sda2 1914 9729 62781988+ 7 HPFS/NTFS
/dev/sda3 * 1 1782 14313883+ 83 Linux

NTFS partition is primary, active and contains boot.ini, ntdetect.com, ntldr, bootfont.bin (I have copied these files from another partition)

Grub settings:
menu.lst:

title Win2
rootnoverify (hd0,1)
savedefault
makeactive
chainloader /ntldr

title Windows
find --set-root /ntldr
chainloader /ntldr

title=Win3
rootnoverify (hd0,1)
chainloader +1

title Win21
rootnoverify (hd0,2)
savedefault
makeactive
chainloader /ntldr

title=Win31
rootnoverify (hd0,2)
chainloader +1


But I can't load Windows using each of these menu paragraph...

All I have are:

Starting up... and nothing (only blinking cursor)
or Error 15 file not found
or Error 17 cannot mount selected partition

Have You any ideas?
Thank You in advance.

Your fdisk output does not show xp partition as active, sda3 is marked as active as denoted by the asterisk (*). You need to change this. Your first partition is a swap partition and your third partition (sda3) is your LInux partition.

Your entry for xp should be:

rootnoverify (hd0,1)
chainloader +1

This assumes you have Grub stage1 file installed to the mbr and pointing to the remaining Grub files on (hd0,2).

sda3 - it is my first partition, not third, see fdisk listing (Start and End)

Please help me get window XP again. I am a beginer in linux.
