Check again for all of the UEFI, CSM or LEgacy BIOS settings you have on any of the BIOS setup tabs, expanding them so we can see every choice. If you can take camera snaps and post them back using the paper clip icon, we can help you better. Otherwise type the choices out in full.

In many cases it requires a Legacy or CSM setting to even install Win7 in UEFI mode.

Edit: Anshad provides a BIOS update below to give you the needed settings. Watch the video to understand how to apply them.

Better to Bypass UEFI to Install WIn7 since UEFI confers almost no benefits and plenty of headaches we see every day here.

How is the USB stick formatted? If stuck with UEFI, use Option One from UEFI Bootable USB Flash Drive - Create in Windows.

I would recommend watching Acer official video guide on how to enable "Legacy" support.

Changing BIOS mode from UEFI to Legacy


Further research reveled that Acer released a recent BIOS update for your model which will enable "Legacy" mode. For your convenience, here is the direct download link.

Windows 7 Ultimate x64

So i have installed the bios mentioned above, changed to legacy bios.
Cant install windows from USB = No bootable device -- insert boot disk.

Changed back to UEFI, and now windows loading files, but as soon as i get to windows loading, i get a red bar in the top of the screen, and it freezes.

any thoughts on that ?

Please reply to multiple steps I gave you which were ignored. It would be installed now if you'd interacted like thousands before.

Windows 7 Ultimate x64

Since you edited your post, i thought you didnt want to see Gregrocker!

Boot mode: UEFI - ( and now legacy cause of the update )
Sata mode: AHCI ( nothing else )

No csm available.

USB stick is formatted with Rufus in this post -> UEFI Bootable USB Flash Drive - Create in Windows

1st attempt. ( Legacy boot mode )
After i updated bios to also support Legacy, the usb stick used as above gives the error " no bootable device "

2nd attempt. ( Legacy boot mode )
Formatted usb stick with rufus to " MBR partition scheme for bios or uefi " this worked on another laptop i have with CSM enabled.

But with the E1-510 acer, it said " no bootable device ".

It seems that when i switch to " legacy mode " it cant see my HDD

3rd attempt: ( Uefi boot mode )
Changed back to UEFI, now the usb stick is loading windows files, but freezes up at " windows loading " with a red bar in the top, see picture.

I cant follow the guide " bypass uefi to install win7 " since the installation progress freezes up at loading windows screen"

I hope this answer your questions, and thanks for helping

It says UEFI Boot for the mode but there are no UEFI devices to choose in Boot Priority order. There should be a UEFI flash stick or DVD choice to boot or it will not install.

What choices appear when you select Legacy BIOS?

Try DVD install.

If you can't get to the step to delete all partitions then boot Partition Wizard CD to Quick Wipe the HD for MBR Legacy install, create Primary NTFS partition to Modify>Set to Active then try Legacy install from DVD.

what I did

I was having all sorts of weird driver issues, and I solved them by using my 2.0 usb port instead of the 3.0, or eSata port. Hope it helps.
