Andrew Lee Posted October 18, 2020 Share Posted October 18, 2020 (edited) Hey, so I tried to run Vista on a USB Hard Drive after flashing the install.wim with Windows Easy Install. I got this BSOD message. I think it might be some sort of USB driver that needs to be loaded during boot. Currently I'm booting on CSM/Legacy mode, UEFI doesn't really work since it gave me an error message as well. Which gave me a "0xc000000f" message which is "The boot selection failed because a required device is inaccessible".

jaclaz Posted October 18, 2020 Share Posted October 18, 2020 The 0x0000007b error means "inaccessible boot device" which translates to "for some reasons the driver for the boot device did not hook it or didn't hook it fast enough". The needed driver is normally disabled/set in the wrong group. You need *something* that sets correctly some keys/values for the USB driver in the Registry: https://web.archive.org/web/20161130182451/http://www.911cd.net/forums//index.php?showtopic=22473 https://github.com/vavrecan/usb-boot-watcher jaclaz Link to comment Share on other sites More sharing options...
