First do a full backup of Windows. You paid for it. You may later find you must use Windows for one application or want to sell system and buyer only Wants Windows.
If you do a Lenovo backup it may offer to delete #8 the PBR_DRV.
Partition 1: WINRE_DRV - Windows recovery Partition 2: SYSTEM_DRV - ESP or required for UEFI boot by all systems. Partition 3: LRS_ESP - Lenovo specific .efi files Partition 4: Unknown 128MiB partition - required by Windows. Partition 5: Windows10_OS - Windows main c: drive Partition 6: ext4 - Linux Partition 7: linux-swap Partition 8: PBR_DRV- Lenovo backup Partition 9: Unallocated 1MiB - not a partition, rounding on unallocated space. If you have done the full backup, you only need 2, 6 & 7 for Ubuntu (and #2 & your data, configuration/settings and list of installed apps in #6 should also be backed up), but then may want /home or data partitions to keep operating system separate from data.
