Today, I won’t emphasise to review MiniTool partition wizard’s each and every feature. It’s indeed a great partition software! We are more interested in resolving certain practical issues.

Recently, I found many people have the same question about windows update 1803. If your PC turns off when you are still writing to the disk, your Windows upgrade fails, and you receive an error message: “INACCESSIBLE_BOOT_DEVICE”

How to fix the above error? There are primarily two ways to fix this error:

1. Fix Bootrec /Fixboot Access Is Denied on GPT Drive

  • From the initial Windows screen, accept the default settings for the language to install, the time and currency format as well as the keyboard or input method. Next, click the Repair your computer link instead of Install now.
  • Select Troubleshoot and then Advanced Options.
  • Select Command Prompt.
  • Type diskpart and press Enter key.
  • Type list disk and press Enter. Now pay attention to the disk number and identify which one is the boot disk. Usually, it is Disk 0; if not, find the disk number in your own case and remember to type the correct one in the following relevant steps.
  • Type select disk 0 and press Enter.
  • Type list volume and press Enter. Now pay attention to the volume number of the EFI partition.
  • Type select volume N and press Enter. Also, type the one in your own case instead of N.
  • Type assign letter=N: and press Enter. N: can be replaced by any drive letter that is not taken by any partition. Remember which drive letter you assign here for it is rather useful in the rest steps.
  • Type exit and press Enter to leave diskpart.
  • Now type N: (the drive lettered you just assigned) and hit Enter.
  • Type format N: /FS:FAT32 and hit Enter.
  • Type bcdboot C:\windows /s N: /f UEFI and hit Enter.
