Which USB mode should I choose when reinstalling the system from USB disk?

Select USB-HDD mode when making a USB boot disk.

USB-HDD: Hard disk emulation mode, the C: drive is displayed after DOS startup. The U disk created by HP U disk formatting tool adopts this startup mode. This mode has high compatibility. Some computers that only support USB-ZIP mode choose USB-ZIP mode.

U disk boot is a technology that starts some backup and restore, PE operating system and other software from the U disk. Most computers support USB booting. It can play a big role in system crash and quick system installation.

Other USB boot modes:

1, USB-HDD

Enhanced USB -HDD mode, the C: drive is displayed after DOS startup, with extremely high compatibility. The disadvantage is that it cannot be started on computers that only support USB-ZIP.

2. USB-ZIP

Enhanced USB-ZIP mode supports USB-HDD/USB-ZIP dual-mode startup (depending on the computer, some BIOS may display C after DOS startup : drive, some BIOS may display A: drive after DOS startup, thus achieving high compatibility].

The disadvantage is that some computers that support USB-HDD will regard U disks in this mode as USB-ZIP to boot, thus reducing the compatibility of large-capacity U disks above 4GB.

3. USB-CDROM

CD emulation mode, it does not need to occupy the drive letter after DOS startup, and the compatibility is average. The advantage is that XP/2003 can be installed like a CD. Production generally requires mass production tools corresponding to the specific U disk model/batch number. For U3 disks, there are general mass production tools online.
