So, what would you like to do, Kari? Did Windows finally boot, and start there? Switch to Linux Mint, as
@Vrai suggested? It is possible that another distro may boot in spite of Windows being in hibernation, if you have another USB prepared or want to make another. But I don't think Mint will run any better than Zorin with 2 GB of RAM... not if you picked Zorin Lite.
You need to boot on something to erase Windows. You can erase and stop, or erase and install Linux. But I think Windows is messing you up in 2 ways: hibernation is one, and the PCR7 is another possible issue (that seems related to encryption with Bit Locker).
Your call... pick a direction and all of us will help get you there.
