Clean Install of Windows 7 64 Bit Freezes on "Starting Windows"...

Clean Install of Windows 7 64 Bit Freezes on "Starting Windows"...

-Just to be clear, I'm still trying to install the OS, not that it was installed and now hangs-
-Also since it came up, I'm trying to avoid a 'legacy'/mbr boot if at all possible, I've seen it work on another machine so it is possible apparently...-

-From looking into it, seems the firmware needs to have 'Int10' (related to graphics) for windows 7 to use UEFI correctly, and if it isn't supported its up to you to figure out how to get it there-

I wrote in most of the details below but in short - a fresh installation ~attempt~ of Win7 64 freezes/hangs on "Starting Windows" (when the 'dots move around' - and becomes totally frozen) indefinitely.

-Basic Info-
Laptop : Toshiba Satellite Radius P55W-B5112
Toshiba provides Win7 64 drivers on website : yes (so it would seem to be possible)
SSD State: completely wiped and re-initialized as GPT while plugged into a different working system
BIOS Notes: secure boot is off, boot mode is UEFI (not a lot of options in the bios, you either get UEFI or CSM)

Bootable iso was made in Rufus

I've re-tried a few times, becomes stuck at effectively the same time every time. Seems to work with a windows 10 bootable iso just fine for whatever reason.

Any ideas as to how to fix this are appreciated.


UPDATE:
Tried a ssd with a working full win7 64 uefi/gpt into the laptop, hangs on 'starting', took the blank drive into the other system, installer works fine...I guess its the mobo?

Hello,

That is a Windows 8.1 laptop, so it is probably using Fast Boot or Safe Boot in the BIOS. Go into BIOS and disable Safe Boot, then afterwards, try booting to your chosen installation media.

Already addressed that.

Anyway, more research is showing its related to 'int10' support (or lack thereof) in the firmware. From a different site, "Windows 7 calls BIOS INT10 even when it's booting from UEFI, no matter what video mode the system supports. Windows 7 works at UEFI mode as long there is INT10 support in the firmware."

Looks like I got lucky on the 1st machine, will have to work for this one.

Hi

In that case use legacy aka CSM boot option

means changing Rufus settings as well.

Well, not a lot of point in installing it then (I'll add that clarification to the post) for me. I'm just going to have to figure out how to 'include int10' in the iso I guess.

Is your BIOS up to date?
On some laptops UEFI mode means Windows 10.
If you want to install Win 7 you should try CSM to install as Legacy-MBR.

Hi

You also need to insert ISRT drivers,

Install Windows on System with MSATA and ISRT
