Cant boot from CD or USB
OptiPlex 7010 (End of Life)
Hello, I'm trying to run Linux Mint live but for some reason I cant get it to boot from CD, I've verified and authenticated LM 22 Cinnamon, I've even purchased the DVD from Linuxcollections.com. But when it tries to boot up I get a bunch of Gibberish on the screen and then nothing happens, I then tried the LM 22 XFCE and it is also gibberish but its green in color. I've also tried booting from the USB but get an error message: "Selected boot device failed, Press any key to reboot system." Oddly I have a DVD LM 20.1 XFCE that I burned from a previous computer and in runs fine,(That's what puzzling me). Thanks.

Hi
The usual thing is LEGACY/SECURE boot options in the BIOS.
Other times is the checksum values being different, corrupted download or burn procedure.
Windows 10 PowerShell and LibreOffice Calc & Writer to make a HASH of IT.
PS C:\>get-filehash and enter the path to the ISO file.
PS C:\> get-filehash
cmdlet Get-FileHash at command pipeline position 1
Supply values for the following parameters:
Path[0]: U:\Downloads\openSUSE-Leap-15.6-DVD-x86_64-Build710.3-Media.iso
Path[1]:
Algorithm Hash Path
--------- ---- ----
SHA256 A74D4072E639C75CA127DF3D869C1E57BCC44A093A969550F348A3EAD561FE4F U:\Downloads\openSUSE-Leap-15.6-DVD-x86_64-Build710.3-Media.iso
PS C:\> "A74D4072E639C75CA127DF3D869C1E57BCC44A093A969550F348A3EAD561FE4F".ToLower()
a74d4072e639c75ca127df3d869c1e57bcc44a093a969550f348a3ead561fe4f You can use LibreOffice Writer to Convert to lower case of course.
Open the openSUSE-Leap-15.6-DVD-x86_64-Media.iso.sha256 in Writer, copy & paste the checksum into cell A1 of Calc,
then the powershell version into cellA2. =IF(A1=A2,"YES","NO")
a74d4072e639c75ca127df3d869c1e57bcc44a093a969550f348a3ead561fe4f
a74d4072e639c75ca127df3d869c1e57bcc44a093a969550f348a3ead561fe4f
YES
You may actually see (probably) that it matches without the formula being applied.
Linux Command Line and LibreOffice Calc & Writer to make a HASH of IT.
$ sha256sum and enter the path to the ISO file.

Hi
Also the mention of RAID 6 indicates a problem with BIOS settings, more than a corrupted media.
You may want to try selecting AHCI mode?

Hi, Thank you ann_droid for replies, I will double check BIOS for that, secure boot was disabled...I did set USB in the first boot sequence and started using the rear USB ports in back of machine (apparently preferred method because directly connected to Motherboard). Still Mint 22 did not want to boot, even after verifying and authenticating via Linux Mint Windows verification tutorial., I tried Cinnamon, XFCE and Mate...a no go, I did try LMDE cinnamon and it booted no problem.....I then tried Debian Gnome, XFCE, Cinnamon, Mate, No problem whatsoever....I'm really leaning into Debian Cinnamon....It does have more of a Windows feel.
My plan is Duel booting Windows and Linux on 2 separate HDDs....Thank you so much for info on how to verify....Debian is pretty vague on verifying and I'm a noob at Linux and Shell commands....I will try your method, once again thank you!

Hi
Thank you for the kind words.
Next is not a direct answer to the problem....
IF you use Ventoy to boot with, it can be created for MBR or GPT....
AND because there are 2 options for Secure Boot (ON or OFF) and 2 options for Partition Type, you can only get it wrong 3 times at worst, the 4th must be successful.
It will prove the type of boot choice you need for the other media you have created.
If in doubt please ask.

Thank you for suggestion!! I've heard about Ventoy, but have never tried it, I used balenaEtcher and then tried Rufus...there is also an option in Rufus for MBR or GPT..I believe default was MBR, But Rufus still wouldn't boot LM....only LMDE and Debian Editions,,(I'll most likely stick with Debian) Thank you ann_droid for all your help (I totally love that user name!)
Regards John.
