Hello,
I am sure many of you wonderful people have seen questions relating to this - and if this has already been answered, then please don't hesitate to tell me to shut the hell up and do my homework on this forum (whilst, hopefully, pointing me in the right direction

)
I recently purchased an Acer Aspire 3 Laptop - 4GB of RAM, 1.1GHZ piece of **** processor and Windows 10 Home Pre-installed. I was fully aware of what I was buying - an attempts to downgrade from my mid level gaming beast to lead a more debt free life (if one can read through the lines

)
The point: I HATE Windows 10. With a passion. The design of it, everything. I LOVE Windows 7. I couldn't ask for a better OS.
I purchased a serial key and program download of Windows 7 professional from softwaregeeks.co.uk - so I could install it on this barely 3 day old laptop. Suffice to say, their response to why this install wasn't working was - 're-download the ISO image + NO REFUND..........' so, no luck *insert eye roll emoji here*
Originally, when loading from a bootable USB drive of Windows 7 - (followed the instructions to the T! FAT 32, GPT seperation etc) - it presented me with this ungodly error:
File: \$WINDOWS.-BT\Windows\system32\winload.efi
0xc0000428
Info: The digital signature for this file couldn't be verified.
I perused websites for a while - figured out that I needed to enable boot from F12. And all of a sudden, this **** of an error message dissipated. However, a security boot lock became enabled - so I killed it off with my weapon of choice, and then, finally - Windows 7 booted from my USB stick... I was so very excited, that I had managed to figure this issue out by myself.
Then, the Windows 7 start up screen simply wouldn't move beyond this... like stuck in some petty, never ending argument, looping in on itself until the end of time.
I had disabled the secure boot, set the password. Where so many before me had succeeded at this point, I have failed. And I am now clueless as to why.
So I figured I would message you good people (and hopefully entertain somewhat) about some trivial BS (in the grand scheme of things) in the hopes you could help me out and point out what it is I am not doing... I admit - I have had 4 tins of beer and feeling a little tipsy, however, I am still pretty coherent and want to get this working! so I don't have to pay the PC guy down the street £50 to sort this out for me when I KNOW there are people out there who can help me out! (P.S. I'm a full time MA Student - so, not in a full time job, hence the lack of enthusiasm for wanting to spend my monthly food budget on a tech guy!)
Any help welcome! And if you made it this far into the marathon of my words, then good on you - and secondly, thank you!!
