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:

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.
