Specs: core i7-6700 250gb SSD drive with Windows 10 Insider builds (Dev channel) 1TB HDD (mostly unused) Gigabyte motherboard GA-H170-HD3 16gb RAM Nvidia graphics (2gb) There is a TPM slot on the motherboard (17 out of 18 pins) - I initially failed the Win 11 checks, but then the Dev build was waiting on Tuesday for me to install: - and so I did... and it took forever... Then I hit the MEMORY MANAGEMENT issue... and the SETUP FAILURE issue... and the FAULT IN NONPAGED AREA issue... Now I can't get past any of those issues, Windows 10 Rollback doesn't rollback, I cannot bring up Windows PE or RE, my original installation disc won't get past the MEMORY MANAGEMENT issue, yet I was able to get into a Windows 7 pre-install environment where I ran Startup Repair which ran for 2 hrs the first time before telling me nothing was wrong... I've installed Windows 7 on my HDD & have tried upgrading to Win 8.1 & 10 but can't get past the first reboot... I've downloaded, installed & ran 2 separate partition tools but don't really know what to do without further borking things up... I've even tried 2 separate Linux rescuers, & still don't know what to do without stuffing things up! As well as the infinite reboot cycle, I'm going around in circles online trying to find out what to do, without actually finding out much beyond the same old stuff or solutions which assume you can still boot into the Windows repair scenario... I haven't tried out youtube for that though. Funnily enough, I'm writing this on my Windows 10 laptop, which is a 10th generation i5 & thus able to run Windows 11 quite well, but I don't dare try in case something like this happens again... CAN ANYONE OUT THERE PLEASE HELP ME?!?
