When booting, it suddenly just goes to (initramfs). NOTE this will reset the VM ie you lose everything on it. I didn't research yet a way to just recover without losing data.

1. type blkid ... and look for something that has ext4 (ie looks like a filesystem)
2. fsck /dev/sda1 -y (modify this for your disk path ... this should check and fix the corrupt partition
3. reboot -f

...

When transferring from another computer, It says you are in emergency mode. .. journalctl -xb to view system logs... ... Press Enter to contimuie. This is probably because it is looking for a shared folder, which has changed.

You need to edit the boot instructions in the GRUB menu (the black screen with text that appears for a few seconds when you first start the VM).

• Restart the VM. 2. As soon as it starts, tap the e key on your keyboard repeatedly until you see a screen full of text.
• Use the arrow keys to find the line that starts with linux. It usually looks like this:
• linux /boot/vmlinuz-... root=UUID=... ro quiet splash
• Move your cursor to the end of that line.
• Delete the words ro quiet splash and replace them with:
• rw init=/bin/bash
• Note: rw tells Kali to let you edit files, and init=/bin/bash tells it to skip the login screen and go straight to a terminal.
• Press F10 (or Ctrl + X) to boot with these settings.

Then

• Open the drive list: nano /etc/fstab
• Look for the "Bad" line: You are looking for any line that mentions a secondary drive, a shared folder, or an old "swap" partition that might have had a different ID on your other Kali machine.
• Comment it out: Put a # at the very beginning of that line so Kali ignores it.
• Save and Exit: Press Ctrl + O, then Enter to save. Press Ctrl + X to exit.
• Force a Reboot:
• Since you bypassed the normal system, you have to "force" it to restart:
• exec /sbin/init (or just restart the VM from your VirtualBox/VMware window).
