PC1: ryzen 5 3600, MSI B550M PRO-VDH WIFI, 5700XT, 2x8gb 3200mhz + 2x8gb 3733mhz RAM (running 3200)

PC2: 7800X3D, MSI Tomahawk b650 wifi, 4080 Super, 2x16gb 6000mhz cl32

win 11 PRO

So i did the following: for PC1 i made a custom ISO: enqueued updates, put in MOBO specific drivers, used the privacy template+ removed stuff like copilot/solitare collection, then changed settings for classic context menu, enabled darkmode, disabled telemetry etc. i also did unattended with a profile and skip all the stuff+windows key

i mounted it with rufus unto a 32gb stick ex-fat format.

it prompted me with the selection of language/time zone, i did that and the whole installation process went without a problem. then upon the PC rebooting i didnt get anything and the PC shut down again and restarted again, only for it to run on a black screen, didnt even get the BIOS pic upon reboot

i made a new ISO, with a very similar process to the first one (almost the same, maybe some settings different) and tried that. again mounted with rufus and the installation process got completed. upon rebooting, the PC got a bluescreen with the following message "boot device not found"

so i tried a third time with another ISO. again, similar setup to the ISO customization i described before. but this time it stopped at the installation process at 2% and got the error code 0xC0000005

i thought there could be smth wrong with the PC itself, so i used the same boot stick (from 3rd attempt)and tried it on PC2. funnily enough it worked without a single problem. the thing is, yesterday i had installed another custom ISO unto PC 1 and that worked without a problem. the only reasons i put on another ISO, is bc in that ISO i think i removed the media features of windows, so redid the ISO and then all the problems happened

does anybody have any idea what could be causing the issue on PC1, when yesterday it was fine and the same ISO works on PC2?
 
Typically when an ISO installs on one PC, but fails on another, the root cause is missing drivers, bad drivers, or driver conflicts.
To confirm it's your driver, temporarily disable RAID mode in the BIOS and repeat the install.

Other than removing a required driver, it's difficult to break your ISO from installing by removing components, or changing settings. Your system might behave weirdly from a bad preset, but it should finish the basic install phase.
