what i did:
  1. bought a new 2tb internal hard drive.
  2. plugged it into my existing system.
  3. formatted it for use with win10, but didnt use it.
  4. got it out and into a new tower where i wanted to install win10 on it with a boot stick.
  5. it showed me 2 drives, one of which, i thought, showed what i formatted on windows. so i deleted and formatted it. now i somehow ended up with it only showing a 2gb drive and partition. i cant "add" or format new space.
  6. obviously i can't install windows on the 2gb drive, even if i format it. how do i get the 2tb "back"? do i need to format it again in my first tower? note that i dont want to recover data, just the drive space.
thanks a lot in advance.

That's very odd.
It's almost like it's not recognizing your hard drive. Do you have another USB drive plugged in?
no, only win10 usb and the hard drive. no other storage device.
im not sure if it recognised 2tb to begin with. but it had two drives, i deleted the MSR one.

Reboot and go into BIOS to make sure the 2TB drive is recognized.
Wait, you said you have two drives...? Unplug all drives except the one you want to install Windows on then check to see if it's recognized in BIOS.

yes, it shows 2 devices: the uefi usb, and a toshiba. that's the device for which it showed me 2tb of space in my first tower.

Please list here all the info BIOS lists for all drives recognized.
i cant really find much info on the hard drives there. i didnt buy the fanciest mb so the bios is pretty basic. its the biostar a320mh with a32es117.bss
all i find is
UEFI: Generic Flash Disk 8.07, Partition 1
P4: TOSHIBA HDWD120

and in the SATA list
TOSHIBA HDWD120 (2000.3GB)

windows disk management says 2GB, but BIOS says 2TB.
It says 2Gb on the partition itself or the whole disk? My guess is you're looking at the partition itself, delete the partition, and create new one. Which should allow you to use the whole disk, if neither the windows disk management tool or windows installer seems to want to properly recognize the whole disk as 2 Tb something might be messed you with the partition table for some reason. Edit: If windows lets you delete the partition, delete it then reboots the machine. Then see if you can create a partition with more than 2 Gb afterwards.

You can try another tool such as Gparted under linux to delete the existing partition.
I havent used that in a while, but some linux live CD images include gparted by default another option is to use the following which includes only gparted so it's much smaller
https://gparted.org/liveusb.php

Another option would be to look at the drive manufacturer website for any tools they might provide to diagnose the drive.

it shows 2gb before and after partitioning. deleting the partition doesn't help, if it were a 2gb partition only it would probably show me the rest as unallocated space. it doesn't. bios is the only place where it shows 2tb now.
i think i messed up smth with the mbr/msr. i tried to redo it with an online instruction, but it didnt help. i guess i will just send it back, cost me a lot of time already.
anyway, thanks everybody!
note to self: just dont mess with things you dont understand and try to make everything perfect...
