Windows Boot Manager Screen
Hello,I am having problems with direct booting into Windows 8 installed into a VHDX file.This is a four-partition UEFI boot on a GPT drive. EFI files are residing on a second partition of disk 0 (the ESP partition) in the EFI folder. The boot virtual disk is residing on the fourth partition of that disk 0.When I turn on the PC, it shows black screen after the BIOS POST screen. No Windows 8 boot menu, no other information is displayed. However, if I press Shift+F12 (or F12) to start Dell BIOS Boot Menu and choose Windows Boot Manager from the UEFI part ofthe boot menu, Windows 8 starts to boot without difficulties.How do I make Windows to boot automatically without having to select Windows Boot Manager in DELL BIOS boot menu?I believe I messed up with boot sector somehow. What needs to be fixed provided that Windows 8 will boot into VHDX file?Thank you.Well this is the world we live in And these are the hands we're given.
When I turn on the PC, it shows black screen after the BIOS POST screen.Try investigating the scope of that symptom. Some are aware that they still have keyboard functionality even though they can't see anything and they may even have sound which means that it they could navigate to the Accessibility button they couldopen that menu and hear comforting words.; )FWIW the safest procedure that I can think of for this scenario is the following loop: Shift-Tab, Shift-Enter, wait (if the harddrive seems busy as a result of the Shift-Enter wait until that settles down.) The idea wouldbe to end up at the Advanced Options screen.BTW nice that UEFI can allow you to force the Boot manager's menu. I have been assuming that users would need to use bcdedit to do that.HTHRobert Aldwinckle. Hi Robert,Thank you for your response!It seems to me that the problem is with boot code that seems to contain reference to the boot manager that is missing from the partition it is referencing to.This PC is using native VHD boot from a GPT physical drive. TheVHD virtual disk is NOT a GPT.
It's a MBR disk.The VHD drive is located on the separate partition with the boot code. That is the boot code and the boot manager are located on separate partitions.I have a similar setup where both the virtual and physical drives are GPT drives and everything works fine.In fact, that VHD drive is not a GPT drive just but the reason I moved it from another non-UEFI PC.I am thinking of the following:1.
How can the answer be improved? Change OS name in Windows Boot Manager. Click on Edit Boot Menu. Now, select the operating system you want to rename, and click on the Rename button. You can now rename the entry there itself. While here, you may also want to select Skip the boot menu, if it is not already selected – as was the case with me. Once you have done this, click on Save Settings and restart you computer.
Booting from Window Setup and patching the boot partition on the VHD disk using diskpart DISKPARTSELECT VDISK FILE=C:WIN8.VHDXDISKPARTATTACH VDISKDISKPARTLIST DISKDISKPARTSELECT DISK XDISKPARTLIST PARTDISKPARTSELECT PART XDISKPARTACTIVEWhere X is the VHD disk and its primary partition correspondingly.It seems like the following happens:1. BIOS looks up for the boot code on the fist device: physical hard drive, partition 22. The boot code successfully executes and points to partition 4 on that hard drive.It looks like the boot code does not point to the boot manager on the partition 1 within the VHD drive!If using diskpart gives nothing, I plan to image that VHD using ImageX clean the VHD, convert it to GPT, and apply created image to its system partition 4.What do you think?Well this is the world we live in And these are the hands we're given. The issue solved.Somehow, updating DELL Latitude 4310 BIOS from rev. A11 then running Automatic troubleshooter in Windows 8 Boot Manager fixed the issue.Additionally, I changed POST settings in BIOS from Minimal to Automatic for it to be configured by OS (as per DELL).Now I don't have to press F12 in order to point UEFI BIOS to Windows Boot Manager. The screen remains black for some short time but now that it switches to loading Windows Boot Manager and it no longer hangs black for forever.Well this is the world we live in And these are the hands we're given.
