SOLUTION

Add the original ScopTel ISO, as a DVD drive in Hyper-V.

Boot the Hyper-V system, and at the boot prompt, type “linux rescue”.

Follow the prompts to mount the existing ScopTel installation, and get to the shell.

Run the following command to make the installed system the root (/) environment:

chroot /mnt/sysimage

 

 

View the contents of the /etc/grub.conf file to note the exact version of the installed kernel, which will be used in the next command:

cat /etc/grub.conf

 

Run the following command, replacing “VERSION” with the version you noted from the output of the grub.conf file:

mkinitrd /boot/initrd-VERSION.el5.img VERSION.el5 --preload hv_storvsc

--preload hv_vmbus --preload hv_utils -f

 

For example, if the grub.conf file noted that the kernel was “/vmlinux-2.6.18-348.12.1.el5,” the version number is 2.6.18-348.12.1. The mkinitrd command would then be the following:

mkinitrd /boot/initrd-2.6.18-348.12.1.el5.img 2.6.18-348.12.1.el5 --preload hv_storvsc

--preload hv_vmbus --preload hv_utils -f

Type “exit” twice to reboot, and your system should boot normally
