I've gotten Error 11 on second time with a different hdd plugged in. The first time, I booted it up to test the program, I seen XP install blue screen, so I was like ok, it works, I shutdown, removed two hdds and plugged in the one hdd I wanted XP on, this is when Error 11 took place. After editing everything then I got Error 15 even just with the hdd I wanted xp on, plugged in. (A). I started a fresh day restarting from scratch, unplugged everything except the hdd I installed too and the USB card reader too SDHC Class 6 flash card. 2006 mobo. With the procedure (A), I've managed to get XP installed on too my hdd. Suppose the program will have to be redone for every new install of xp. Thanks, ilko_t for the help .
