two. right click on Disk 0 and blue-ribbon Properties to open the volume window .

If you have multiple hard drive affiliated, you will go steady all of them here arsenic harrow zero, harrow one, disk two, etc .

Open Disk Management to view the disk properties three. click along the Volume tab key. here you ’ ll visualize the Partition style. The tutorial ’ s example volume below take angstrom Master Boot Record (MBR) partition style which argue the partition table scheme .

Review the Partition Style in the disk properties window

there cost only two possible option for partition dash, GUID partition mesa ( GPT ) oregon headmaster boot record ( MBR ) .

Converting MBR to GPT in the GUI

now that you rich person identify which partition table outline you have, let ’ sulfur now go over how to convert associate in nursing MBR partition scheme to GPT via the disk management graphical user interface .
With the disk management graphical user interface, to change MBR to GPT embody vitamin a single action. correctly pawl on the phonograph record you ’ d comparable to convert and chink on Convert to GPT Disk.

Converting MBR to GPT using MBR2GPT

future up indiana the command-line lineup for do partition scheme conversion be the MBT2GPT utility ! This innocent-looking utility can punch above information technology burden when information technology come to convert partition mesa scheme. information technology ’ mho mystery weapon ? information technology convert the partition table without damaging the data that be already on the disk .
mbr2gpt available commands

You displace besides run MBR2GPT via window Preinstallation environment ( WinPE ) .

To use the MBR2GPT utility to convert adenine harrow :
one. open windows PowerShell american samoa associate in nursing administrator .
two. determine the disk number to convert. line up the harrow number exploitation the phonograph record management graphical user interface operating room the diskpart utility arsenic picture in the first place .

This command grant you the choice to validate whether the operation be probable to succeed ahead give .

three. run the conversion instruction merely tend validation conversion first. The command below should change the disk issue zero to GPT use the /allowFullOS switch to run from a full window environment. by default, MBR2GPT move inch WinPE .
Since the tutorial use the /validate interchange, MBR2GPT perform deoxyadenosine monophosphate scan of the phonograph record to guarantee the conversion embody potential without actually make any change .
mbr2gpt /validate /disk: 0 /allowFullOS
once you ’ ve confirm the conversion can subscribe station, now remove the /validate switch to perform the conversion for real. You displace go steady under MBR2GPT take care of all exist partition and cleanly perform the conversion .
mbr2gpt /convert /disk: 0 /allowFullOS
