Converted VM is black screen

Postby chicagotech » Thu Aug 03, 2017 2:00 pm

Q: I use disk2vhd to convert my windows 10 machine to a VM (Generation 2). It give me the message: "No x64-based UEFI boot loader was found". Then I try to created Generation 1. I get a black screen. How do I fix it?

A: Microsoft has an article talks bout this issue. Quoted:
Windows 2008 R2 (Vista, Windows 7, Windows 2008)

We’re going to fix the entire boot path, despite what part of it is broken. Go find an ISO or DVD of any of the operating systems just listed in the title. Prepare to boot your VM from this media. We’re going to use the recovery console. We’ll assume you are using Windows 7 media.
1.Attach the Windows 7 installation disc to the virtual machine disc drive, and then start the computer.
2.Press a key when you are prompted.
3.Select a language, a time, a currency, a keyboard or an input method, and then click Next.
4.Click Repair your computer.
5.Click the operating system that you want to repair, and then click Next.
6.In the System Recovery Options dialog box, click Command Prompt. 1.If an operating system is not found simply continue anyway

7.Type the following command in this order to set your system straight: 1.bootrec /fixmbr (Fixes MBR)
2.bootrec /fixboot (Fixes Boot Sector)
3.bootrec /scanos (Scans for Windows installations to add)
4.Reboot! (Type Exit)

8.If you still do not boot into Windows, or do not have a boot menu, or something is still wrong, follow steps 1 – 6 again. For step 7 type this instead 1.bootrec /rebuildbcd (Rebuilds entire BCD… not a really big deal)
2.Reboot! (type Exit)

You are now either booting into Windows, or you are not… Any blue screens I cannot help you with at this time. Search the internet for a solution, and in the meantime I intend to write an article on this as well. Comments welcome as always.
