When installing the WIN8/WIN8.1/WIN10 system on a USB flash drive or CD, many users encountered an issue that could not be installed, prompting "Unable to install Windows on partition 1 of drive 0", and formatting partition 1 does not resolve, which prompts windows not to install to this disk. The selected disk uses the GPT/MBR partition format, what is this? The following small series to analyze the cause of this problem and how to solve them.
First, the reason analysis
WIN8/WIN10 system Add Quick Start function, pre-installed WIN8/WIN10 computer default is UEFI boot and GPT hard disk, the traditional boot mode is legacy boot and MBR hard disk, uefi must correspond to GPT, the same legacy must correspond with MBR. If the BIOS turns on UEFI and the hard disk partition table format is MBR, it cannot be installed, and the BIOS shuts down UEFI and the hard disk partition table format is GPT, and Windows cannot be installed.
(Note: Converting a partitioned table will erase all data on the hard drive!) )
Second, unable to install Windows workaround on drive 0 partition
1. Press and hold SHIFT+F10 to bring up the command prompt window at the current installation interface;
2, enter DiskPart, press ENTER to execute;
3. Enter the DiskPart command mode, enter the list disk return, list the current disc information;
4. To convert Disk 0 format, enter select Disk 0 to return to the car, enter clean, delete the disk partition;
5. Input convert MBR, enter, convert disk to MBR, input convert GPT to GPT;
6. Enter exit to exit the command prompt, and return to the installation screen to continue the installation system.
