Installing XP on a 14.1" wide T61.

I have a T61 with vista home premium installed. I want to install XP on it but when i run my XP disk it doesn't find my HDD. What's goin on?

 

Please refer to my guide for a clean installation of XP.

From my Guide(in sig):

So you've done the long process of downloading and organizing all your drivers onto a storage USB Drive or separate disc. Now insert the XP Install disc. Restart. Hit F1 when you see the ThinkPad Splash screen. Enter Bios. Set the following settings in BIOS:

Config > Serial ATA (SATA) > Set AHCI to Compatibilty
Hit Esc
Hit Esc again
Startup > Boot > Move ATAPI CD0 to the topmost spot (1)

Hit F10 to save and exit. The computer restarts

Upon bootup, hit any key to boot from disc.

 

thank you ill try that

 

OK, good luck!
