I need to install Windows 7 on my ASUS T100TA which has a 32-bit EFI without Legacy Boot option. Windows 8.1 is very lagging, so why don't try install Windows 7?
First, I prepared 32-bit Windows 7 install USB, entered into BIOS, disabled Secure Boot, but the USb didn't boot.
I also tried other way: Created Windows PE 5.1 bootable USB with extracted Windows 7 ISO which successfully booted. I then opened Command Prompt and ran Windows 7 setup, accepted license, selected "Custom install", deleted ALL partitions from 32GB Flash drive, created new partition, but it can't install Windows 7 there (missing Intel SD Host Controller driver).
Can anybody help me unlock the Legacy Boot option or give me the BIOS-emulation bootloader?
1AFAIK, there's no way to add BIOS/CSM/legacy support to a firmware that lacks that support, short of replacing the firmware. Even if you did that, it wouldn't help with driver support issues, which is your problem. To that end, you should check with ASUS, or with whoever made the controller for your "disk" (really flash storage) device. Even if you get this support, AFAIK Windows 7 won't work well on a tablet because of user interface issues. Personally, I'd stick with Windows 8, return the computer for a refund/replacement, or maybe look into running Android on it. – Rod Smith – 2015-10-10T16:48:40.200
I did clean Windows 8.1 install (not recovery), installed all drivers from ASUS website, installed Office, Windows updates and Chrome, It works well (better than ASUS pre-installed Windows copy), yesterday I tried install Ubuntu 15.10, but no success (booted into "Try Ubuntu", updated grub via terminal, started setup, but after create user account setup hang, after 20 minutes I got "read error" message. – DJ Vozny – 2015-10-10T17:27:13.383
