How to mount the Windows host drive from within an Ubuntu

Assuming NAT is used, and the host port is 192.168.234.2, the host's 'C:' drive (i.e. using default share C$) is mounted to Ubuntu's folder /mnt/hostc

• First create the mount point:

  mkdir /mnt/hostc chown zumaubuntu:zumaubuntu x

• (note that you can really put this anywhere, and call it whatever you want)

• zumaubuntu is the name the user in Ubuntu.

• To just mount it once, you can issue the mount command like so: sudo mount -t smbfs -o uid=1000,gid=1000,username=ZumaWin,password=ZumaPass //192.168.234.2/c$ /mnt/hostc

• This assumes:

• zumaubuntu's uid and gid are 1000. If you don't know what these are, use the 'id' command at the terminal.

• ZumaWin and ZumaPass is a Windows users who has Administrator access (since the C$ share is used)

• However, to make the mount permanent, edit the /etc/fstab file and add to the bottom:

//192.168.234.2/c$ /mnt/hostc smbfs uid=1000,gid=1000,username=ZumaWin,password=ZumaPass

Grub rescue

If the computer is kicked into the grub rescue> prompt.

This information is from: https://help.ubuntu.com/community/Grub2#Command_Line_and_Rescue_Mode

1. Type set

You should see where grub is looking to boot from

2. Type ls

Shows you all the devices. Do an ls on each one, adding, /boot/grub to the end of the path, until you find the right one.

3. Set prefix and root (substituting X and Y to that of the device that you found containing the boot/grub folder)

   set prefix=(hdX,Y)/boot/grub set root=(hdX,Y)

4. If you do it right, then you should be able to type:

   insmod normal normal

5. Boot into Linux and then type:

   sudo update-grub

6. Then type this, replacing x with the boot device:

   sudo grub-install /dev/sdX

If you're not sure what the boot device is, run a disk utility in Linux. On my machine, it's /dev/sda
