What is "it"?

What is the A: drive? Is it formatted as FAT something?

Hey,
thanks for answering!
"It" is the Vbox Manager. I can create a VM with 2GB mass storage but not more than that. Ive tried with different iso files.
My A:drive is formatted as FAT32 with almost 100GB capacity.

Also if i try to run the VM with 2gb storage it says i have to enable virtualization in my BIOS, but its nowhere to be found. Neither by searching for it in the Bios nor in the CPU section.

Hope you can help me

The max size individual file you can store on any FAT drive is slightly less than 4096MB. This is a well known limitation of using FAT32.

Some implementations of FAT use signed 32bit arithmetic, so this will fail on files over 2GB. It's possible VirtualBox caters for the least common denominator.

Executive summary: format the drive with exFAT or NTFS.
