So far I've not seen any absolute commonality. I'll shortly be making backups of the MBR/partition tables of all my VMs and maybe I'll feel a little better afterwards.īut it seems to me that something must be going on that is causing this to happen to more than one user in recent weeks. Please just take it as being similar to having a broken arm but invisible to the naked eye - it can be fixed but it takes time to heal. If you have no experience of such a mental tunnel vision then you won't understand. Yes, this is silly/stupid, but it is how I am at the moment. Unfortunately this causes me to worry that it might happen to me. Yes, we're only taking about 2 or 3 users posting about a problem out of many, many thousands, but it is clearly not an isolated incident with only one user being unlucky and encountering some random issue. The installed OS is still there, just waiting to get booted someday.Several people have posted about problems with VMs not booting with "no Bootable Media found" errors recently. Virtualbox Dmg No Bootable Medium Found Virtualbox Windows 10I've checked again and the harddisk isn't empty or anything. I've also tried to change from PIIX3 to ICH9. Besides, it worked fine until today and I haven't changed anything expect the upgrade. There's no way I have misconfigured anything in this regard (mind you, I have some experience with setting up Virtualbox VMs). 'No bootable medium found' is the answer. I turned off EFI to see why, because the EFI shell doesn't tell me why *it* is starting instead of the OS. Now after the upgrade I got into the EFI shell after booting. I had set it up as an EFI (ticked that box). I had one VM installed, Linux Mint latest version. I don't remember which version I came from, but it couldn't have been older than 4 weeks, since that's how old my pc is. Already have an account?
