Hello,
so I've pulled all my hair out already trying to install Windows 7 on my Acer E1-510 laptop in UEFI mode.

The laptop came with Windows 8.1 preinstalled, and I've used that for quite a while before deciding to wipe it and clean install Windows 10.

The laptop does not have a CD/DVD drive thus I can only boot installation media from an USB drive.

The original installation was in UEFI mode, and in order to switch it to Legacy BIOS so I could install my Windows 10, I had to download an update for the BIOS which made such a switch available. It installed and ran fine for some time.

Afterwards I decided to switch over to mainly using Ubuntu. So I wiped the drive, saving only crucial data like photos and such to a backup USB drive. I have installed Ubuntu 16.04 in UEFI mode with GRUB2 as my bootloader. I swapped back to UEFI mode, and disabled Secure Boot.

Since some of my applications which I use are unavailable for Linux, I want to keep a Windows 7 x64 installation on a small partition in a dual-boot environment so I can reach for it if I feel the need for some of my applications.

So borrowed a friend's PC to clone my Windows 7 DVD to my USB drive in GPT format, so I can boot from UEFI. At first it was immediately giving a winload.efi missing error, the Setup couldn't boot, but when I re-imaged it to my USB drive it started to work.

It shows up a progress bar saying "Windows is loading files" and then reaches the animated logo. As soon as the animated logo starts, the screen freezes and I get a red bar on top of my screen, along with my fans starting to spin full-speed.

I've tried booting the same USB on my friend's PC, and it gets to the entire installation without any issues, I've reached the point where I actually choose which partition to So basically - install to.

A quick Google Search about the red bar yielded me that Windows 7 doesn't support GOP, which from what I've read is the functionality to display an OEM logo while the Windows is booting. In Windows 8.1 / 10, I'd get an Acer logo with the white dots spinning around below it, suggesting Windows is starting up.

I've also read that to bypass that I need to enable CSM in my BIOS, however I could not find such an entry anywhere in the setup utility.

Is there something I am missing? I'd really prefer using Windows 7 to 8.1 or 10 because of the whole Metro layout. I also don't really want to wipe everything and recreate in Legacy mode, I'll consider it as a last resort option.

Thanks for all the help :)

I had to disable Secure Boot to get the system to boot from USB at all, since it would throw a "Security Boot Failed" error. It's definitely off when I am installing...

I havent had any luck personally getting windows 7 to load using a GPT drive, I tried and got frustrated and converted drive to MBR.

If they start selling 2tb+ SSDs cheap then it would be good to know how to do it though.

If I were to convert my drive to MBR right now, would it ruin my current Ubuntu setup? I'm also concerned about the partition limit; I'd need at least 4 partitions (Ubuntu Swap, Ubuntu itself, Windows, and Data).



To be honest, by the time we get those I think Windows 7 will well die out.
