So I have SONYSYS partition with EFI files(273mb) , windows recovery environment(1.5gb), EFI filesystem(273mb), microsoft reserved, basic data, another two windows recovery environment partitions (1gb and 32gb)
Is one of the partitions damaged so I cannot boot from harddisk OS or just my settings messed up? At this point I have no clue on fixing windows boot

Exactly which option did you chose for installation? "Erase and install..." or "install alongside" or "something else"?

The latter is very unlikely because that requires some knowledge about partitions.
If "Erase and install..." had been chosen and the installation actually started, you wouldn't have now the partitioning layout you comment above.
"Install alongside" would've tried to shrink the Windows system partition and install Lubuntu in the resulting unallocated space. In this case forcefully stopping the installation would have very bad results.

Since this problem seem to be related to a Windows OS, I'm out.

I'm here to help with Ubuntu and Linux problems, not Windows OS. Mods should probably move this to a more appropriate thread.

It could also be an UEFI problem. You set the boot order to boot from DVD to run the live disk, now the UEFI no longer wants to boot from the hard drive. If that's the problem, it shouldn't be too hard to fix, but very hardware specific.

Since all Windows issues, moved to Windows sub-forum.

Boot your Windows repair flash drive and run Windows repairs. You may need chkdsk more than once on all NTFS & FAT32 partitions.
And you may need to run the full set of commands to repair boot.

What do you mean by needing chkdsk more than once ?

[oldfred]

Some have posted that chkdsk does not always fix everything on one pass. So you have to run it more than once.
