 Just to see whether this Laptop will at all support Windows 7 in ANY mode? 

If your laptop meets minimal Win7 system requirements AND can boot from USB HDD (choose disk in UEFI BIOS) - of course you can experiment with HDD on cheap, using VHDs for convenience. It should, since UEFI support indicates newer laptop model. Or burn a DVD from Install ISO if you have a burner. Don't set chaotic multiple goals though, structure your tasks in stages, try to understand what exactly you do and why...  :)

UEFI Firmware

Securing the Windows 8 Boot Process

 

Install UEFI OS from ISO to VHD(X) in running UEFI Windows (8.1 or 7 Ultimate/Pro):

 

- boot UEFI Win8.1 from laptop GPT disk's C:\ volume, and hook up USB HDD to the laptop

- in Disk Manager initialize USB HDD as GPT, create & format NTFS partition on it & label & mount to G:\
- create fixed VHD(X) 20Gb on USB HDD, initialize as GPT

- create, format and label 100MB Fat32 EFI System, 128MB MSR, and large NTFS Windows 7/8 partitions on VHD(X)

- mount EFI volume on VHD(X) to V:\ , and NTFS to W:\ , make it active
- mount Win 7 or 8 Installation ISO to E:\ with ImDisk or Windows Explorer

- open Command Prompt as Admin
- check available OS versions on the ISO using DISM GUI or DISM
Dism /Get-WimInfo /wimFile:"E:\sources\install.wim"
- mount WIM to O:\ (optional to add drivers):
Dism /Mount-Image /ImageFile:E:\sources\install.wim /index:1 /MountDir:O:\WIM (/ReadOnly)
- apply WIM image to VHD(X)
Dism /apply-image /imagefile:E:\sources\install.wim /index:1 /ApplyDir:W:\
- dismount WIM and ISO in Windows Explorer
Dism /Unmount-Image /MountDir:O:\WIM /commit (or /discard)
- add boot environment to VHD(X)

cd W:\Windows

bcdboot W:\Windows /s V: /f UEFI
- add VHD(X) to the laptop's boot menu

cd C:\Windows

bcdboot W:\Windows
- dismount VHD(X) and Shift-Restart your PC from it to Specialize new OS

 

Notes:

- in case of Win7 as laptop's main OS, use VHD instead of VHD(X), install WAIK to add DISM, add ImDisk for ISO mount

- in UEFI mode, selected Windows version 32-or-64 bit must match the PC architecture

- to Migrate BIOS Windows to UEFI, Restore your OS to HDD or VHD(X) using Windows Backup or package like Acronis instead of applying install.wim

 

 

Cannot say if it can be of any help with your issue, but it is possible that "between the lines" of this thread:

 

http://reboot.pro/to...in-bios-to-gpt/

it can be found something of use. :unsure:

 

 

Is that were "Outside of Asylum" is?  :yes:   I couldn't ask a question there. Some folks posted in June 2014 that "the registration gate" on reboot.pro is closed, and apparently it still is. The site was for sale last year, traffic dropped dramatically before that, so may be they decided to close the gate forever, no new members allowed?   :whistle:

No, that is actually the Asylum.

I reside outside of it.

And my gate to it is closed as there is no way (anymore) to have some meaningful exchange of ideas (apart the strictly technical field) with a number of residents.

 

About site being for sale (or not) and/or increases or decreases of traffic (or Alexa ranking for that matters) those are essentially Nuno's business.

 

Instead of all this (senseless)  suppositions, have you actually tried registering there?

 

No less than three new members registered today, so I believe that there are not any issue of any kind with it.

Sorry, I didn't catch what was that about - Blue Ribbon?  :rolleyes: Thanks for the link - as always Content Rich stamp from The Finder.

I will try to find some DVDs burn Windows 7 on them and see if the boot on UEFI. Any particular MSDN / Digital River ISOs you'd recommend / know of that will WORK?

Any x64 ISO supports UEFI boot.
Remember: this is about basic testing still: does machine works at Windows 7 UEFI?
I expect: boot.wim is loaded to RAM and PE is processed:
either hangs next: vga.sys can't connect to VGA bios. Then ignore UEFI Windows 7 at this machine.
or does boot and Shift F10 is possible: UEFI Windows 7 is possible
 

I have a spare HDD (cant open laptop).. But I can attach via USB.. DO you think I should try installing and booting Windows 7 off that on a Partition? Just to see whether this Laptop will at all support Windows 7 in ANY mode?

Yes, this was another idea. Be aware, windows 7 doesn't support USB booting.
There are different approaches to circumvent this: different machines requires different solutions.

Basic testing: clone the Thinkpad HDD.
Boot from USB HDD at Thinkpad. A BSOD 0x7b is a good sign so far.

Connect the USB HDD to the Toshiba. Turn on the machine, press the boot select hotkey.
Do you get a USB HDD twice? One should refer to BIOS mode and antoher to UEFI mode.
Select the non UEFI mode. Again a BSOD 0x7b would be a good sign so far.
