I’ve been using Antergos(64 bit) on my lenovo b50-10 laptop for almost an year now and I’ve never had any problems. Unfortunately for college reasons I had to recently install windows 7. I resized one of the partitions I had, formatted it as NTFS and installed windows on it. The installation went fine and now I can boot Windows if in the Bios screen I selecte the the Uefi mode.
After that I tried to boot into legacy mode and see if Antergos was still working but grub was corrupted and was displaying the grub rescue terminal(as I was expecting) so I followed this other post’s solution in order to restore it (https://forum.antergos.com/topic/1380/solved-missing-grub-command-reinstall-grub/5).
The steps suggested in the post seemed to work except for the mkconfig command which generated some errors:
Generating grub configuration file ... ERROR: mkdir /var/lock/dmraid ERROR: mkdir /var/lock/dmraid ERROR: mkdir /var/lock/dmraid ERROR: mkdir /var/lock/dmraid ERROR: mkdir /var/lock/dmraid ERROR: mkdir /var/lock/dmraid ERROR: mkdir /var/lock/dmraid ERROR: mkdir /var/lock/dmraid WARNING: Failed to connect to lvmetad. Falling back to device scanning. done
I tried to reboot and grub was working again but the menu wasn’t showing any antergos entries (it was displaying only the entry for an android os I tried to install some time ago and I never deleted. this option was showing also before I installed windows).
I’ve actually tried several other solutions that I found on the internet but none of them seem to work.
At a certain point I’ve even found an old grub.cfg file (the one I had before installing the android os, for which I had to create a new entry) but when I booted it gave me an error saying something like “file vmlinuz not found”.
In order to make you understand you better this is what I get if I run $parted /dev/sda print
Model: ATA ST500LT012-1DG14 (scsi) Disk /dev/sda: 500GB Sector size (logical/physical): 512B/4096B Partition Table: gpt Disk Flags: Number Start End Size File system Name Flags 1 1049kB 3048kB 2000kB bios_grub 2 3048kB 253MB 250MB fat32 boot, esp 3 253MB 4349MB 4096MB linux-swap(v1) 4 4349MB 29.3GB 25.0GB ext4 5 29.3GB 179GB 150GB ext4 6 179GB 431GB 252GB ext4 7 431GB 500GB 69.1GB ntfs msftdata
where sda4 is my root partition, sda5 is my /home, and sda2 is /boot partition. sda6 is just a partition on which I keep other stuff and sda7 is windows.
If you need anything else I can post it cause I can still access the all the files inside the antergos’ partitions. Hope you can help me.
