Display the list of the disks in the system: list disk.Boot from the Windows installation (DVD/USB) media with (suitable Windows 10 or Windows 7 installation image), and press Shift+F10 on the Windows Setup screen to open the command prompt: Excellent! Plug in a small USB flash drive or an SD card. Restart the computer and make sure that the BIOS can not boot from the hard disk with the GPT table. Thus, the conversion of partition table into GPT has been successful! Moving the Windows Bootloader to the USB Flash Drive Writing secondary GPT to LBA address 83786657… Writing primary GPT and protective MBR to LBA address 0… Such partitions will remain bootable after conversion. 0 at the end of the physicaldrive shows that disk 0 should be converted. Thus, it will not be possible to install or boot Windows from a GPT disk on older computers with classic BIOS firmware. However, only 64-bit Windows versions installed on motherboards supporting the new UEFI specification (Unified Extensible Firmware Interface) are able to boot from a GPT volume. No need to use logical partitions subject to various errors.Īccording to the official Microsoft documentation, all its OSs starting from Windows Server 2003 SP1 support volumes with GPT markup as the data disks.Thus, the disk partition structure will not be lost if the first disk sectors are damaged High reliability achieved by duplicating the partition table at multiple locations on the disk and verifying the partition table using cyclic redundancy check (CRC).Support for up to 128 partitions on the disk (only 4 partitions in MBR available).Support for hard drives over 2.2TB (maximum available GPT disk size is 9.4 ZettaBytes (9.4 x 1021 byte)).

What advantages does GUID Partition Table (GPT), a new format of table partitioning on a hard drives, gives? GPT allows to bypass a number of limitations of the classic MBR Partition Table.
