The only thing I did after installing the SSD was booting into the system and checking in gparted if it sees the new ssd, it did. Did a reboot and got out of memory error after the boot screen.
Also I had a 1 TB SSD in the system, took it’s cable and put it on the new drive, then installed a new cable on a different sata port and put it on the old ssd, for better cable management. At first boot there wasn’t any problem, I saw both drives, even checked the contents of the old ssd.
It took a minute or more to boot with the out of memory message. Tried rebooting after that, now it doesn’t say out of memory, just takes a long minute to boot.
edit: It did display the out of memory message a few more times. Then I ran sudo grub-install
and sudo grub-mkconfig -o /boot/grub/grub.cfg
after that I didn’t see that error, just it still takes a minute to boot. It hangs after the inital ramdisk message, the drive usage led is lit up constantly for that time.
