Pc won´t boot from CD anymore, maybe Recovery Manager ?

If VMWare Player is configured the same as Workstation (I mainly use Workstation), the default is to boot from the hard drive before the CD/DVD drive.

If the Player menu allows it, select to boot the VM directly to the BIOS (in Workstation, this is VM >> Power >> Power On to BIOS). Then verify that the CD/DVD drive is set to boot before the hard drive. Also, check the settings for the VM and make sure it's configured to use the physical CD/DVD drive on the host (if that's what you're using). I usually use ISO files for booting because it's so much faster and easier.

Are you saying that the ASRM is activated on the VM's hard drive? If so, that should in no way affect the VM's capability of booting from the CD/DVD drive or ISO file.

Thank you for the comment.
But please forget VMware at that point. It´s only the reason why I discovered my problem.
My PC will not boot from a (bootable) CD any more, with or without VMware.
Put a bootable CD in the slot, BIOS is in "boot from CD first" mode, but he always starts from disk.
Cause I suspect the ASRM, I posted this note. Maybe there´s a way to completely remove that thing. I guess, ASRM has occupied some special disk sectors and/or modified the boot process.

The ASRM resides completely on the hard drive. It does not take over any BIOS booting options.

Does the CD drive seem to function correctly in Windows? You can browse CDs, etc.?

Have you tried using a different CD drive?

Some BIOS's have separate boot order options (a "main" menu order section and sub-device settings). Have you verified that both (if they exist) are set correctly?

Does the computer have a BIOS Boot Menu key (F11, F8, etc.)? If so, have you tried using that to directly select which drive boots and bypass any default BIOS settings?

Thanks for your patience!
It was the 2nd idea. Using a different drive (E instead of the first one D) it works well.
I don´t have a clue why, BIOS didn´t recognize an OS there.
