Trying to install W10 on an LGA775 w/o USB booting.

[phongle123]

Hello, I am trying to install W10 on an old LGA775 socket motherboard. I am using a W10 Bootable USB that is usable on my AM4 board but simple gives me a single underscore when I try to boot it on my LGA775 board.

 

I have looked at the few options the LGA775 bios offers and there doesn't seem to be a switch to enable legacy or USB booting. I do not have a W10 disk to boot from or a DVD reader for that matter.

 

What are my alternatives? Trying my AM4 SSD on the LGA775 also resulted in an underscore (not a press any button to try again error). The PC originally had Windows Vista and that booted so the PC is working.

Your current USB-install is made for UEFI-based computers and you need to make one for legacy BIOS, download iso2disc and if do not already have a Windows 10-ISO download one of those as well.

 

Start Iso2disc, point to your Windows 10-ISO, chose Burn to USB flash Drive then Partition Style MBR and Bootdisk Type Create Windows Installation USB Click Start Burn and after some time you should be set.

Is your flash drive formatted in MBR or GPT?

 

LGA 775 i believe will only work in MBR sinve that system is too old to do UEFI.

Correct. UEFI boot wasn't a thing until Ivy Bridge in 2012. It was added to some degree to Sandy Bridge boards but nothing older.

Download the ISO from Microsoft, don't create the stick immediately. Then download and run Rufus. Select the ISO, select MBR partition map and set target system to BIOS. One it's done, try again. 

 

if that doesn't work, burn a DVD
