Windows 7 won’t boot off external HDD

@SIW2 i did as you said, i slipstreamed the usb 3.0 drivers into the iso, and the updates, but it gave an error, iso already had the updates, so i used winntsetup to install the windows, used the script, CSM support on, BSOD, 0x7B, i dont know if i did something wrong

@SIW2 microsoft does not provide windows 7 iso anymore, i have to use one from archive.org, im not sure if it work this time...

@SIW2 i found a iso from archive.org, had no updates, i slipstreamed usb 3.0 drivers and updates you gave me, yet still BSOD 0x7B, i cant find a official microsoft iso from windows 7, ntlite said its successful as you can see, and i used your script, yet no success

@SIW2 i might sound inpatient but, you aren’t really replying, is there no hope anymore? The 0x7B indicates there is no 3.0 drivers so there is disk errror, the 0x7E pasts the disk.sys but stops at achix64.sys, my freind told me to switch the sata mode into achi, but there is no option in the bios, i have no idea what to do

@SIW2 I think the closest we got is with the 0x7E iso, it passes the disk.sys, it stops at achix64.sys, do you have any idea about what it could be?

@SIW2 BIG UPDATE!!: I have finally succeeded, thanks to your windows 7 installation media, I have made an iso, and it works both internally and externally (via VHD and normal installation ) (externally only works via VHD) I’m making a GitHub repo for a guide how to do this, I will credit you in the repo along with some other people like my friend @Sevoos, who helped me allot, why make an GitHub repo? I really wanted to do one for a long time, I don’t know why, the ISSUE was indeed, ahcix64s.sys, which is an AMD driver, just removing them from the drivers fixes it!
