Do I need to repartition the hard disk to change win7 to win 10? Is the format the same?

There are many ways to upgrade win7 to win 10, and not all of them need to format the hard disk. The main upgrade methods are as follows:

1, online upgrade, this way does not need to format the hard disk, will retain the original win7 hard disk format.

2. Upgrade by installing a CD-ROM. This method does not need to format the hard disk, and users can choose whether to keep the original files from the source.

3. Completely install zdwin 10, not an upgrade, but a new installation. Therefore, it is necessary to delete the original partition of win7 and re-partition and format it.

Extended data:

Win 10 hard disk partition:

1 and computer hard disk partition tables with win 10 system pre-installed are GPT by default, because all new motherboards are in UEFI mode. When win 10 system is installed in UEFI mode, the hard disk partition table must be GPT.

2. If win 10 is installed in Legacy mode, then the hard disk partition table is MBR, and the win 10 system supports UEFI+GPT or Legacy+MBR installation and use.
