Win7 Uefi setup
« on: December 16, 2017, 07:08:35 AM »
Hello

SOrry that i post here but i cannot found the correct place.

I have a laptop  installed is windows 10
and try to install from boot usb windows 7 x64.

I have read i must disable "Secure-boot" and Uefi is enable

Now use i Rufus with option Gpt partition and fat32 to create a win7 usb disk from a Win7 X64

If i boot from this usb come the screen from setup "windows loading files" >> windows is starting"

And it freez.

I have google for a solution but not any good found has any an idea?

Greets,

That Acer model does not look like an easy case :

No any way to switch to the legacy BIOS mode?

Hi ragdog,

the installation of windows must be done differently, in your case, there is a dropping of the usb connection, so everything freezes. You need to run LiveCD, make a hard drive formatted, copy all the installation files to the root of the disk, restart the system and install as usual without external sources, then just delete the extra files  :P

There was a trick that at some point you need to pull out and insert again your usb drive, but I dont remember at what stage of the installation exactly  :icon_redface:

Im not sure if the system will boot after you change gpt to mbr  :(

here reported that it was possible to install in the ufi mode with

the solution is in fact to have csm (compatibillity support module) support also enabled but have uefi set to load first.

I have had success with booting setup from a UEFI USB with a Windows 7 DVD also in the drive, it boots from USB, starts setup, can't find the USB any more, finds the DVD and continues (this was just a copy of the Windows 7 files, not a bootable DVD)
I can walk on water but stagger on beer.

I have also had a problem with the existing hard drive being MBR. Can you boot to recovery and use diskpart?

select disk 0   <<<<whatever disk number you are using, usually 0
clean
convert gpt

Maybe try and convert it to MBR (at least temporarily) and see if setup gets any further. If it does, you're probably not booting from an EFI USB drive.
With most BIOSes if you press the "select boot device" key (F11, F12?) it should list the bootable drives, on my BIOS it explicitly shows UEFI-bootable drives e.g.

Kingston Data Traveller
UEFI Kingston Data Traveller <<<<<

HI

Found the problem

"Windows 7 setup dosn't support GOP only hardware: freeze at loading vga.sys"

This is not compatible with Uefi mode, it works only this bios works with Uefi/Csm mod.

Ok i found out it give solution with add a gpo driver and it can boot in Uefi.


thanks,
