# How to mount HVM disk # How to mount LVM image
You want to read your HVM disk (ex: you did some errors and can't start the HVM ). You want to read your LVM image (ex: you did some errors and can't start the VM ).
First, read the partition table: 1: make the image available for qubesdb. (dom0)
```bash ```bash
sudo parted /dev/YOUR_VG/YOUR_VM unit B print # Example: /dev/qubes_dom0/vm-debian-9-tmp-root
dev=$(basename $(readlink /dev/YOUR_LVM_VG/YOUR_LVM_IMAGE))
qubesdb-write /qubes-block-devices/$dev/desc "YOUR_LVM_IMAGE"
``` ```
Example: 2: Create a new disposable VM (dom0)
```
$:sudo parted /dev/windows-vg/vg-game-root unit B print
Model: Linux device-mapper (thin) (dm)
Disk /dev/dm-138: 314572800000B
Sector size(logical/physical): 512B/512B
Partition Table: msdos
Disk Flags:
Number Start End Size Type File system Flags
1 1048576B 105906175B 104857600B primary ntfs boot
2 105906176B 314571751423B 314465845248B primary ntfs
```
Then mount the partition you want:
```bash ```bash
sudo mount -o loop,offset=105906176 -t ntfs /dev/windows-vg/vg-game-root /mnt/ qvm-run -v --dispvm=YOUR_DVM_TEMPLATE --service qubes.StartApp+xterm &
``` ```
3: Mount the partition you want to, and do what you want with it (disp)
```bash
mount /dev/xvdiX /mnt/
```
4: Umount and kill the VM (disp)
```
umount /mnt/
```
5: Remove the image from qubesdb (dom0)
```
qubesdb-rm /qubes-block-devices/$dev/
```
