acer erecovery management

hi. i'm just confused about one of the options of the acer erecovery management,
the "restore operating system and retain user data" option. i'm thinking of
using it actually.

my current OS is windows7. there is also a backup OS for windows vista in my
laptop (the one in the hidden partition).

i just want to ask: if i use the "restore operating system and retain user data"
option, will i be able to retain and use my windows7? and not the vista?

thanks... hoping for an immediate reply.

Hi, Acre eRecovery Management should ask you which OS you want to restore.

You should create backup for Windows 7 also, before you do anything.
