This is now my fifth time installing. Very frustrating. Dell R630 with Raid. I have Ubuntu on a usb drive. Every time I get the installation completed, it asks me to remove the media and press a key to reboot, which I do. When it reboots, I am told that “no boot device available or operating system detected”. Sometimes I get a Grub screen also with errors related to the hard drive. This drive is a brand new SSD. So, perhaps I am not setting up the drive settings in the BIOS correctly, or the RAID setup correctly? I don’t understand how it installs completely then reboots and loses everything. Please help.
Installed again. Did the ubuntu update, rebooted. Same thing. Getting a Grub screen with boot options. When I select the first option, *ubuntu, I get these errors:
error: disk ‘hd0,gpt2’ not found
error: no such device: bunch of letters/numbers
double free at 0x59bd6de0
Aborted. Press any key to exit.
Please help! This happens every time!
Just offering info as I do not have a Dell R630

The answer mentions a bootloader called Clover but I have not used this utility.
Apparently, Clover is a fork of rEFIt.
rEFInd is also a fork of rEFIt and I can safely say that rEFInd is a solid tool.
You can install rEFInd on a usb stick (for portability) - it’s worth its weight in gold

Worth investigating, methinks…?
error: disk ‘hd0,gpt2’ not found
Does that drive and partition exist when you run sudo fdisk -l from the Ubuntu live usb? That bunch of letters/numbers is the Universally Unique IDentifier which is unique to each partition and does not exist. Run blkid from the Ubuntu usb. Do you see that UUID in the ouptut? What partition are you installing to? Did you boot and install in UEFI mode. When you boot the Ubuntu usb and run sudo parted -l, do you see an EFI partition? What option did you select for device for bootloader installation?
