Questions regarding z580's partitions (FreeDos version)

2013-03-14, 15:16 PM

Hello everyone!


I've bought a Lenovo z580 (FreeDos), I wanted naturally to wipe the HDD and partition the 1To to install windows and some linux distros.


What I've noticed is there are 4 partitions already there: first one sda1 has boot,lba flags, /dev/sda2 lba flag, a huge unallocated space (expected) and then an ntfs parition /dev/sda4 LENOVO_PART with a "diag" flag, I assume that it's for recovery, can I just wipe them and start from scratch? (the fat32 doesn't contain any EFI related info) and if not, which ones should I keep?


Thank you very much!



here's the output of fdisk -l through a live medium:



Disk /dev/sda: 1000.2 GB, 1000204886016 bytes
255 heads, 63 sectors/track, 121601 cylinders, total 1953525168 sectors
Units = sectors of 1 * 512 = 512 bytes
Sector size (logical/physical): 512 bytes / 4096 bytes
I/O size (minimum/optimal): 4096 bytes / 4096 bytes

hi Acid_Rain,


Welcome to the Lenovo Forums.


Most computers that are sold without an OS shouldn't have a LENOVO_PART on them as it should just be the  /dev/sda2 created by FreeDos. Try to check if you have a Windows sticker on the front or back part of the unit.


If you have a Windows Sticker, try to:

1. Press the One Key Recovery button to restore the original OS.

2. Create a Gparted Live CD or USB and set the LENOVO_PART as active and restart the PC to boot from the recovery drive.


If the recovery attempt fails, you can just wipe all partitions and install a fresh copy of Windows on an unallocated or NTFS formatted drive.



Hope this helps.
