System_drv disk suddenly appear

System_drv disk suddenly appear with disk letter and not appear on disk manager

 

dont answer with open disk manager and remove the disk letter, it doesnt appear on disk manager as a disk and i cant connect my external harddisk anymore because the letter g: is hijacked by this system_drv disk

 

this happen when i installed windows update, dunno what update because i installed about 10 or more update at once

Re: System_drv disk suddenly appear

Hi there, Billy-

 

Thank you for writing in to the Lenovo Forum - happy to have you here today.

 

SYSTEM_DRV is Lenovo's current version of the standard Windows 7 BIOS system partition. By default a Windows 7 install creates two partitions, the system partition and the Windows partition. This configuration is necessary for Bitlocker and for operating more than one OS from the disk.

 

Thus far Lenovo UEFI systems are shipping in Legacy BIOS emulation mode i.e. not UEFI boot mode. It remains to be seen what Lenovo's default partition scheme for UEFI boot will be.
