Uefi boot setup

Can anyone fill me in on how to get this setup? Is it not possible installing from USB?

 

Answered my own question. Only works from DVD.

 

Still no luck. The install keeps freezing and if it does actually finish windows freezes at the logo unless I have legacy boot options enabled.

Everything is fine in legacy

 

USB has to be formatted fat32 to do so.

 

Never did get it working. Windows install kept freezing. Tried other media and checked all the checksums to no avail. Has anyone besides me tried this? Anyone think it's a hardware problem? Or maybe something with the new bios.

 

You are installing Win 7 right? look at this

Installing Windows 7 on UEFI based computer - Ask the Core Team - Site Home - TechNet Blogs

Windows 8 worked out the box under UEFI for me. I did wipe out EVERY partition that came with my laptop. Dell installs Win7 under BIOS and thus you have a Master Boot Record set up which you need to remove for UEFI boot to work, whether Win 7 or 8.

Did you wipe out all your partitions first?

 

while modding the bios of my l502x I was able to do uefi boot by enable the option in bios and picking a FAT usb stick with the following folders (efi and boot) and rename the efi shell file too bootx64.efi

EFI\BOOT\bootx64.efi

Treied Win7 and Win8. Wiped all partitions/drives. Even went as far as removing the msata drive.

 

I'm not clear on what you're saying. Are you saying you replaced the contents on the bootable windows 7 usb stick with this folder? The current Efi folder is as follows efi/microsoft/boot/

 

no no, I didnt replaced anything.

I just said I was able to boot some stuff from a usb drive using that method, though that info may help on this topic ^^

 

Oh, well I can get the windows CDs to boot fine. They go through the initial transferring of files with the shaded grey bars then when the windows logo comes up right before the install screen it freezes. The 4 little dots just get stuck in mid air.

 

mmm, it looks like installation corrupted files or something like that.

did you also ran memory tests?

I remember similar issues while installing windows xp on my old pentium 4, the installer got freeze at the middle of the installation, one of the memory modules was damaged, after removing it it was the fix.

by doing some memtest you can ensure it is not a memory issue.

if could be also hdd issues, but not sure.

 

ran the full dell diagnostics the day before with no problems. I can install fine in legacy mode. I tried at least 4 different medias between usb stick and dvd.
