Installed an OS in RESCUE mode and cannot boot to it

[ability_cn]

Hi Guys
I've got a VPS on OVH and I need to install a custom Debian ISO image.
Here are my steps so far.

• Boot to recovery mode
• deleted partitions on sdb

then I run the commands:
apt install qemu-kvm

wget -P /tmp https://URLTOISO.iso

qemu-system-x86_64 -net nic -net user,hostfwd=tcp::80-:80,hostfwd=tcp::443-:443 -m 1024M -enable-kvm -hda /dev/sda -hdb /dev/sdb -vnc 127.0.0.1:0 -cdrom /tmp/URLTOISO.iso -boot d

ssh root@SERVERIP -L 5900:localhost:5900

Once the installer has finished I reboot in to normal mode but It just says "booting from hard disk..." and it just stays here.
any help appreciated.

I installed the iso to sdb

If I install the ISO on a VM on my PC, the only difference I can see is that i get a GRUB loader then it boots.

I dont have a GRUB loader when I restart out of OVH RESCUE mode.

You need a boot loader, how else is your computer going to find the kernel.

Grub isn't the only one, there's lilo, & syslinux, (& probably others too), these are just ones that I've used in the past.

Reinstall your vps via the OVH panel because they should have an option to do a normal install or contact ovh support?

Hi

When I install Debian with the ISO, it does install all of that because it reboots a few times during installation.

Do you know how I can install GRUB and set it to boot from sdb1 as that is where my install is.

OVH VPS dont allow for installing ISO.

Maybe ask here?

Installing Operating System from custom image on OVH VPS ( CentOS 8 Tutorial)

In theory this should work with any custom ISO, however I tested only with CentOS 8 1) Reboot VPS in rescue mode 2) Connect to Rescue Mode via SSH, unmount /dev/sdb1 and remove all partitions: # lsblk # umount /dev/sdb1 # fdisk -u /dev/sdb > d > d > w 3) Install required packages: # apt...

This is the first rabbit hole I went down. I just need assistance in getting a bootloader going to see If i can get it to boot. the Installation is there.

Have you tried an iPXE type installation over the internet?

Here is a website with bootable installers for many distros. It is a working implementation of iPXE. I have tested them on virtual machines and VPSs, but never had an account on OVH. I have no way to prove that their wide range of installers are genuine, but they appear to be. Look at this website:

https://netboot.xyz

You will need "bare metal" access to your VPS, including a console. That would describe a typical KVM VPS. It will not work with OpenVZ or most actual VPSs with Xen.

If you do not understand this paragraph above, that's okay. Just get a KVM VPS that has a control panel with a console for you to use for installation. VPS providers who use SolusVM control panels usually offer a browser-based console, but I do not know what OVH has.

FYI: I am still learning and experimenting with iPXE-related technologies myself.

Normally, install it, then run

sudo grub install /dev/sdb

sudo grub install /dev/sdb

Should be

sudo grub-install /dev/sdb

then

sudo update-grub
