Why do I have to install windows 7 every time I boot the VM?

[adr34531]

I have Windows 7 installed as a VM using virtual box but every time I boot it, I have to re install it. It takes a lot of time, so is there a way to stop this from happening? I also have Kali linux installed and I don't need to install that every time. Any ways to fix this?

Do you have the virtual boot image set as the primary boot device ?

(If you used an ISO to install the OS, make sure it goes to the drive image you installed it on.
If you installed from a DVD, remove the DVD from the VM.

You might be better off deleting the VM and creating a new one.
If you are installing from an ISO, make sure your boot settings are correct in the VM before you boot it.

(I dont remember the exact location of the setting in Virtualbox, but that would be the 1st place Id look.

If all of that looks to be correct, I would try:
A different boot source (re-download the ISO, check the MD5 to see if it is corrupted)
Possibly a different folder for storage of the VDI (or whatever its called in virtualbox)
Did you customize any settings ?

You really aren't giving much in the way of info....
