Ok so I bought Asus Fx553vd 4 months back and it came pre installed with Windows 10. But it got updated to fall creators update and I am sick of the bugs. Specially because the disk usage is soaring to 100%. I tried a fresh install. Even tried installing an ISO before the creators update but the disk usage doesn't go down.
So I decided to install windows 7. But as soon as it loads the files for installation Blue screen of death pops up saying this version of bios is not fully ACPI compliant.
I already read the previous threads and checked off the details.
My bios is fully updated.
During installation I disable secure boot and csm is enabled.
I already fixed the iso with usb driver problem regarding 3.0 drivers.
I even tried by burning the iso on dvd but it didn't work.
So is there anything I can do to get Windows 7 installed?
