I have a Windows 2008 R2 Core machine in my home lab which is blue screening on each boot and rebooting. This machine has been working and stable for about 2 years now, most recently the underlying iSCSI storage began to have problems and was replaced. There were errors on the disk, however I was able to mount the virtual disk on another machine and run a chkdsk which found the errors and repaired them. After this was done the VM returned to functioning normally until it starting maxing out on memory usage before finally crashing.
Since then it has blue screened and rebooted on each attempt. I have tried the following:
1. Mounting the virtual disk and performing another chdsk - no errors found.
2. Booting in safe mode, last known good --> System Blue screens before completing loading the OS
3. Booting from the install CD and using recovery console - my only option here appears to be to run another chkdsk, this does not find any errors and does not correct the problem.
No backups exist in this lab however I would like to recover the machine if possible. It is a 2008 R2 Core machine running DC, DNS, and file server roles. It is the only DC for my lab. What other recovery options to I have available to me?
