Sorry to dredge up an older thread but I'm new to the XP USB boot 0x0000007b BSOD, and my problems have gone from bad to worse. I've built my BartPE multi-software USB stick and all the apps on it work fine except the XP Recovery Console. I got the 0x0000007b BSOD when the XP Recovery setup got to the Loading Windows screen. A poster at the msfn.org/board offered a modified NTDETECT.COM file to fix it, but after I substituted it I got a "file iaStor.sys could not be found" error and had to abort the rest of the console setup before the Loading Windows screen had a chance to display. BTW, the IASTOR.SYS file is located in my I386/SYSTEM32/DRIVERS folder of the BartPE ISO. I'd appreciate if someone could point me to a more definitive solution to these XP setup issues. Thanks.
