    [ubuntu] Re: Boot loop error msg

    Grub is easy to install from live installer or using Boot-Repair.

    See line #204:

  4. [SOLVED] Re: Ubuntu 18.04 does not see PCle SSD with SATA mode set to AHCI on Acer Aspire 7

    Many also need SSD firmware update.

    And if Windows is installed, did you turn off Windows fast start up?

    Was this using RAID 0 with two drives?
    You then have to erase meta-data on drive.
  5. Re: Problems booting Ubuntu 19.04 on Acer Nitro AN515-42

    Have you updated UEFI from Acer?
    You may have to reset some of the settings you changed in UEFI as it reverts to defaults on update.

    Re: 16.04 will not boot

    If UEFI system, you may have fast boot on in UEFI. Then UEFI does not do any system scan & immediately boots. And you do not have time to press any keys to get into UEFI or UEFI boot menu.

    Re: Cloning SSDs

    Are you going to keep 250GB drive in use?
    If so you must change UUIDs as you cannot have duplicates.

    UEFI or BIOS system. If UEFI with gpt GUID also cannot be duplcated.

    Are you using the correct UUID in Boot stanza. The example just has some old UUID.

    Re: Forcing System boot up

    Nothing really to repair.
    Boot-Repair really is for repair of Linux systems. But with Windows in BIOS mode, it can install a generic Windows type boot loader.

    It would install syslinux which is a...

    If system is broken and even Boot-Repair will not run that is a totally different issue.

    lsblk -f

    Did gdisk show anything?

    If you had LVM that is a major complication. That would be one partition with multiple volumes inside it. But no idea how to recover from that.
    Most say then best to just...
  15. [ubuntu] Re: partition recoverable? or lost - Aomei partition manager

    Since you have gpt, and Windows often forgets to update backup gpt partition table, does this show a mismatch and then you can restore from backup partition table?

    Re: Forcing System boot up

    With multiple drives, I often have to manually edit boot stanza as I boot.
    My hd0 may become hd1, hd1 then is hd2. But boot drive is always hd0, even if sdd or normally hd3 is used to boot.

    Windows has had that issue since Windows 7 and thru Windows 10. It "forgets" to write Linux partitions back to partition table. But data is still there.

    Re: Won't Boot, Long Beep

    You have an UEFI system, but BIOS boot installs.
    Are you sure you have system booting in BIOS mode, not UEFI?

    If you updated UEFI/BIOS, it would reset to defaults and that would change boot mode.
