Debian Stuck at Booting from Hard Disk after installation on KVM

debiangrubkvm-virtualizationqemu

I'm trying to install Debian on Qemu-KVM on RouterOS v5.25

I tried :

debian-10.8.0-i386-netinst.iso
debian-8.11.0-i386-kde-CD-1.iso
debian-live-9.0.0-i386-gnome.iso

on disk image created using : qemu-img.exe create -f raw debian.img 10G

during the installation process, everything is good to the end.

but right after finishing installation and rebooting, it shows the boot screen counting to 4 then it's stuck at

Booting from Hard Disk...

GRUB installed on (master boot record) during installation and i've tried to install it on (/dev/sda).

Note : it's not rebooting itself, it's just stuck.

Here's the boot parameters :

RouterOS KVM configuration :

(for testing) I installed debian-6.0.10-i386-netinst.iso it did install and boot without problems, but nothing higher than this version is booting.

What causes this problem?

You seem to redirect the output of the kernel to your serial port. Remove the kernel option console=ttyS0.

Linux – Ensure USB disk is never sda, even when booting from it

The most reliable answer to this question, that I'm aware of, is to use the newer symlinks that udev can create for you. Udev enumerates the disk drives, and creates several trees with devices - explaining for you what kind of devices they are.

This is located in /dev/disk.

You have, by-path:

/dev/disk/by-path/pci-0000:00:1a.0-usb-0:1.5:1.0-scsi-0:0:0:0-part1
/dev/disk/by-path/pci-0000:00:1a.0-usb-0:1.5:1.0-scsi-0:0:0:0
/dev/disk/by-path/pci-0000:06:00.0-scsi-0:0:0:0
/dev/disk/by-path/pci-0000:00:1f.2-scsi-1:0:0:0-part2
/dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0-part2
/dev/disk/by-path/pci-0000:00:1f.2-scsi-1:0:0:0-part1
/dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0-part1
/dev/disk/by-path/pci-0000:00:1f.2-scsi-0:0:0:0
/dev/disk/by-path/pci-0000:00:1f.2-scsi-1:0:0:0

Which clearly tells you if the device is a usb-device, for instance.

Linux – Stuck at grub prompt after a default CentOS 6 installation

I eventually resolved this problem by following the advice given by Michael above. Zeroing out the first few megabytes of the drive and then re-installing the operating system did the trick. I suppose there was some sort of MBR or partition table corruption at play.

If you are stuck at a grub screen after a fresh CentOS installation, try following these steps:

Insert the CentOS installation disc or mount the ISO.
Boot into rescue mode and enter into shell. Skip any steps to mount the existing file-system.
Run the command fdisk -l to determine the label of the drive you need to zero out (e.g., /dev/sda, /dev/sdb). If you have multiple drives, be very careful to pick the right one.
Run the command dd if=/dev/zero of=/dev/sdX bs=512 count=4000 where /dev/sdX is the drive in question (e.g., /dev/sda, /dev/sdb).
Exit out of the rescue shell and reboot.
Re-install CentOS 6 as per normal.
