Hi,

¨a disk read error occurred¨ appears on screen after choosing to boot into Windows XP from GRUB.

[root@localhost linux]# fdisk -lu

• sda is a 160GB hard disk with quite a few partitions and 3 OSes installed. I am able to boot into Linux and Mac OS fine, but not into Windows anymore. The Windows system is located on /dev/sda1.

I can not recall how exactly have I used testdisk but it once said that ¨The harddisk /dev/sda (160GB / 149 GB) seems too small! (< 172GB / 157GB)¨ or something simillar.

So far I have tried to ¨fixboot¨ and ¨chkdsk¨ from a recovery console on the affected windows partition (/dev/sda1), the plug off power cord for 15 seconds trick, reinstalling GRUB, repairing the MFT and boot sector of the affected partition via testdisk, what next please ?

Thank you!
