my situation:
- the regular SATA HDD with Ubuntu 16 in my IdeaCentre Q180 worked fine until lately. Diagnosis: hard disk failure. I decided to get a new SSD to replace the broken HDD.
- Install with the SSD installed to the internal SATA port, BIOS Setting SATA AHCI and using a standard Ubuntu 18 ISO USB Stick works and the installation finishes with "success, please reboot system now".
- Reboot gives me: no operating system found.
NOW strange: If I unplug the SSD from the internal SATA Port, take out the SSD after installation and put it into a USB (USB to SATA bridge) case and plug this into the IdeaCentre, the system boots without problems.
I used Boot-Repair with many of the available options but with no change in behavior.
Setting the BIOS SATA Mode to IDE or AHCI does not change anything. I also resorted the boot order of devices to all possible permutations - no change.
Anyone with an idea why the SSD does boot via a USB Bridge but not connected to the internal SATA connector?
Thanks.
