Linux mint DVD, USB Flash and external SSD won't boot to desktop
Hi Folks.
I am new to Linux, but I've made some progress. I have been able to create bootable Linux-mint OS on a flash drive, a dvd and an external SSD. Every one of them works fine on my laptop and my friend's desktop. They won't boot to my desktop (except in compatibility mode). It could be because my desktop has a disabled (in WIN7) on-board video chip and Linux is trying to use it. In another forum, it was suggested that a use a Linux-mint cheat code such as radeon.modeset=0 Does anyone know HOW to use this code? Where does it go? I assume it goes in the boot file somewhere. You're help would be appreciated |
when booting, when you get to grub (where you are asked to select your os, or it automatically boots the first entry after some time) press 'e' on the highlighted entry and append that "cheat code" to the line that starts with "linux /boot/vmlinuz....."
if that helps we can discuss ways to make that permanent. if not, we'll find other ways to get your setup working. |

So I can see two ways out of that dilemma - a quick & dirty one, and one that makes sense. Quick & dirty would be to simply plug your monitor into the onboard video adapter. But since I assume you're using an add-on video adapter for some reason, you will want to keep using it. So the better approach would be to go into the BIOS setup and disable the onboard VGA adapter there. Then Mint shouldn't recognize it any more and go on to the next one available, which should be the add-on card you're using normally. Quote:
So the only reasonable thing is to disable the internal video, and to do that at system (BIOS) level, not through Windows. [X] Doc CPU |

Thanks for your response...I think you're right...BIOS is the place to disable the on-board video (other than taking a hammer to it (LOL).I went into BIOS to change my video. I was able to change the order to GFXO-GPP-IGFX-PCI..it didn't make any difference. There is no setting in my BIOS to completely disable the on-board video.
The next step was to attempt to change the boot line in Linux. I pressed "e" and was able to see the line in the attachment. I tried entering the line radeon.modeset=0 at the end of the line and at the end of the "ro"...no difference. The on-board video is: ATI Radeon HD3200 graphics the card that I am using for windows is AMD Radeon HD5700 series. Once I get this issue figured out I intend to install LM on an internal HD by itself so it's completely isolated from the windows HD. I thank you for your help. |
Thanks for your reply.
There seems to be an issue with AMD vireo cards. (See: http://forums.linuxmint.com/viewtopic.php?t=122257) I was able to change the loading sequence of the BIOS to GFXO-GPP-IGFX-PCI, but it didn't make any difference. ( I am still not sure why it didn't make any difference unless LM sees the AMD video driver for WIN and skips it. I am not sure how to load 2 different video drivers into the system. If I could, I'd put the AMD Linux driver in too (it's on the AMD site). I tried loading LM from the boot cd to an external drive when Linux was in compatibility mode, thinking that somehow it might pick up the driver...no luck...no video. My next approaches will be to: (1) try to figure out if there is some way to load the video driver into the LM on the external HD. I just have to find a way to load it as a proprietary driver, when Linux isn't working correctly. and (2) Continue to see if anyone has found a solution to this in the forums. |
ok, so back to your original problem:
did i understand correctly that you have made a usb with linux mint, which boots nicely on your laptop (all the way until the graphical desktop) but not on your desktop computer? so a few questions: - what's different about your desktop computer? - is there any reason to believe that this issue is graphics related, other than your suspicion? - how exactly does it "not boot"? we already established that grub is loading from the usb. that's good. what happens after that, how does it look exactly? have you tried loading recovery mode from grub (might be called differently in the menu)? |
SOLVED !!
I practiced an installation on an external HD (XHD) in case anything went seriously wrong. These are the steps; 1. Format the XHD with the root/home/swap partitions 2. Attempt to boot from the Linux boot cd 3. boot to compatibility mode 4. install Linux to the XHD 5. shut down and boot from the XHD 6. press e as soon at the menu appears 7. At the line that starts with Linux...and ends with quiet splash and add radeon.modeset=0 GRUB_GFXMODE=1280x1024x32 8. Press Cntl X to boot with the added commands. 9. Linux will boot without the video acceleration hardware (a window will warn you of this) 10. open terminal and follow the instructions at: https://www(dot)youtube(dot)com/watch?v=Ka5gBMlo-zo 11. (note the text below the video for written instructions and for applicable video cards) When you reboot from the XHD, everything should work fine. I am sure that some of the steps I did are unnecessary..but I am new at this. I hope that this will help someone else. Thank you all for your help ! You folks are amazing. |
