I have seen many of the Windows 10 upgrades that have gone bad.
I would not neccesarily blame Windows (but the upgrade also seems to have gone ahead in some cases where people select the 'close' cross at the top
right of the upgrade dialog, rather than saying "no" with the button and the system is programmed to assume a 'yes' answer as default).
Frequently the issues are due to malware or existing configurations conflicting with something new, however the majority of issues I have seen seem to
relate to user profile corruption.
If you can't get access even to back up your files, try creating a brand new admin user and log on as that user. This seems to solve most of the
initial Win 10 issues.
If you are happy to try a clean installation (without any previous baggage) for yourself, then ensure your backups are good and download and run the
"Media Creation Tool". Run the tool and create a bootable install USB drive. During the install, delete all the partitions and re-format your system
afresh, just in case there was some odd security or file system corruption.
Because Windows has already installed & activated on the hardware, it should activate automatically after you install when you connect to the net (the
activation is stored in the cloud).
Then comes the process of restoring your files and reinstalling your other programs.
EDIT> I have just seen that your system is in a boot loop. In that case, you probably don't have an activated copy of Win 10, which complicates things
now the free upgrades are supposedly over. There is, however, a way to get Win 10 that will allow you to activate it at no cost but I don't think that
is going to help just now.
Don't loose heart, during the upgrade process the previous version of Windows gets archived and can be restored, even if the Win 10 install gets
borked.. This may be preferable but first you have to get past the reboot loop (which sounds like corrupted files during the upgrade).
Have you tried a system restore or "Last Known Good" boot? I'd give them a go and see if you can restore bootability.
By the way, POST stands for Power On Self Test and it is that bit that the BIOS does before the graphical start-up (like where it counts through the
installed RAM). Newer UEFI BIOS machines may not have a BIOS based POST but it is much the same functionally. It is program code that checks a few
basic components before starting up the operating system.
