I need help as I don't have any knowledge about windows boot process, but I'm willing to learn.
Have an Acer Aspire V3-771 that came with Win8 preinstalled on 750GB HDD. Decided to try to use Dual Boot with Win8/7 combination. Pulled Win 8 HDD added 1TB HDD and installed Win7 Pro. as single OS on new HDD. Much to my surprise Acer has an extra HDD port for an additional HDD.
Installed additional HDD now machine will boot into Win 7 with BIOS changed from UEFI to Legacy and Security boot disabled. System runs stably until shut down - then hangs with screen off but fan remains on until manually shutdown.
Problem: On reboot with BIOS changed back to UEFI and Secure Boot Win 8 will not boot, CD System disk will not boot and freezes with - BCD error 0x0000098. Any assistance will be appreciated.
