Windows 10: Can't boot into HDD or reinstall windows?

So long story short I bought a new SDD and then tried to copy some pictures and files from the old HDD. I don't really know what happened along the way but I must've messed with some security settings and lost access to my HDD. Now I gained back access to it, says those folders I want to access are no longer there and its because they are shortcuts, but the files are definitely still there cause I can still see the used up space on the HDD. So now I'm trying to get back into my HDD but now it won't boot up for some reason... I've tried a chkdsk, sfx scannow, fixmbr and now tried to reinstall windows but I get an error, tried advanced repair also get an error, and for some reason the whole windows32 folder is gone on that HDD idk how that happened. So I'm really lost right now any help would be appreciated! Thanks, and no I don't have any external backups or restore points.. Sadly, and I created an image of the HDD split it on the same hdd so I could work with the one that's not working.

Changing boot hdd

I downloaded PartitionMagic8.0, but the partition i want to make is not bootable.
So the system boots from the old, loud hdd, and when i unplug the old, it doesnt boot.
Any advice or suggestions how to change boot hdd without reinstalling Winxp?

 

Sabertooth 990fx won't boot to windows logo, it shuts down

to boot and enter bios and load windows, any todays PSU (with the correct plugs) will work, AFAIK

to enter BIOS only low wattage is used.
Then, during boot, the HDD and a bit later the videocard card start to demand juice, then the other devices and periphericals... so the total demand during boot up is incrementing step by step, that's why a failure halfway could indicate a PSU problem....
