So I had a problem with booting from a USB so I couldn't install Windows 10 on my new SSD. Then I had the idea of putting the SSD in my brothers laptop, installing windows there and putting it back in mine. The install was successful and everything worked fine. I put it back in my laptop and still, it won't boot. I still can't boot from a USB (even though I used to be able to do that as I've installed Ubuntu before and yes I disabled secure boot, tried changing the boot mode to legacy and I reset everything in bios to default and nothing worked) and booting into anything at this rate is not possible.

I think I ran out of options. What am I missing and what can I do to fix this?

May I ask why that wouldn't work? Based on my understanding, it's just like moving a hard drive from one laptop to another and having all the information on it. And if it's useful, my brothers laptop is the exact same model as mine. Also, I don't know what else to check as far as booting from a USB is concerned. Like I said, I've disabled secure boot, changed boot mode to legacy and did what all guides I've found told me to. I'm especially perplexed because this used to work flawlessly so what do you think could have changed?

Moving a drive with OS between any two systems often fails completely. Laptop->laptop...Desktop->laptop...desktop->desktop.

Sometimes it works, sometimes it fails completely (as you've seen). Sometimes it works partially.
I've seen all three outcomes.

Does that USB install work in other systems?
Does the Ubuntu USB install work in this laptop currently?

The windows USB works for sure as it worked well on another laptop. I tried another Linux bootable USB which also works on another laptop, but not mine. The problem is definitely my laptop.

Hi

What software was used to made the bootable win 10?

I would try the microsoft media creator
There are many other programs which work on most pc's but microsoft is the most reliable
A working win 10 usb should be recognised twice once as a uefi (brand usb) and another without the uefi prefix
If the boot hard disk has been partitioned as GPT not MBR set bios to uefi not legacy and choose uefi usb option
If partitioned MBR choose legacy ( only allowed if boot disk size not more than 2 TB)

Secure boot setting should not be relevant for win 8 or 10 but will need to be off for win 7 and many linux versions


You need to sort out booting from a windows 10 usb or possibly a dvd (in a external usb if necessary)
Before doing a clean windows 10 install

I used the official media creator to make this bootable USB. I am certain it works as it worked on another laptop. The option to boot into the USB shows up however once I select it, it says "EFI USB device boot failed." I've also tried it several times with all the options you recommended and the same exact message gets displayed. Any other ideas?
