Linux On An IMac

I have a Toshiba laptop that will not boot. I get to the grub menu which gives me the option to load Ubuntu, Ubuntu recovery mode, or a couple of memory tests.

If I select Ubuntu I get a black screen with a flashing cursor in the top left corner.

Selecting recovery mode gives me a lot of messages with the last one being "EDD information not available".

The memory test option does not return any errors.

If I try booting Mint from a bootable DVD I get the Mint screen and then it goes gray with a flashing cursor in the top left corner.

Any suggestions?

Hi Guys, I installed a dual boot config. on a 160 gb hdd. The first choice in grub menu is Linux Lite (latest distro) and the second boot choice is Mint 17.1 Rebecca. I'm encountering a situation that when I boot into LL the system boots OK. Then when I try a restart and boot into Mint it seems to be doing OK until the end of the boot process at which time the screen flashes the Mint logo and then goes dark-then flashes then goes dark every second or so-endlessly. After a while I'm sometimes able to get Mint to finish booting by hitting the esc key. Any ideas how to make this screen flashing situation stop and do a normal boot?

Update: Solved the problem by changing the resolution settings to coincide with those of LL....flashing stopped!

LL and Mint IMHO are two of the best distros for a Newbie to "get their feet wet." - I know, I am that Newbie.

OK, I fixed the issue with the download. I installed Linux Mint Cinnamon "Rebecca" 17.1 on the computer. It said it was installed successfully, but when I rebooted all I got was a black screen with the cursor stuck in the upper left corner of the screen. I let it sit for a long time (maybe 45 minutes), did a control alt delete but nothing happened. I had to shut down the computer manually.

I downloaded Mint 15 - MATE and made an iso image DVD disk. Then rebooted with DVD in drive. The followinh happened
Splash screen with Linux Mint on
Then Automatic boot in 9, 8, 7 etc secs
Then Linus Mint 15 in Courier with 4 dots underneath
After 2/3 mins screen turned black, covered in white U letters with Welcome to Linux in background
Then wide red and black horizontal bands
Then a more graphic screen with 2 Linux Mint logos on green and white bands, top one a bit fuzzy. Cursor has a red box around it. Icons for Computer, Mint Home and Install Linux mint 'ghosted' with background showing through
Firefox loads, again ghosted, but cannot access internet even though wifi light lit on computer.

Computer is Fujitsu Seimens Amilo L7320 1.7 GHz and 960 RAM

What is going wrong?

Want to try Linux as computer freezes in Windows XP after about 20 mins.

Help appreciated.

i have an imac 5.1 and it simply will not install linux. mac software is 10.4.11
does anyone have any info on why these computers wont accept the install. i installed refit on the mac and it still wont do it. any info would be great , thank you

I'm trying to install Debian 7.8 on my eMac G4 (700mhz, 640 Mb RAM). I've tried multiple methods but I keep running into problems one way or another. Since my eMac only has a Sony CD-RW drive and a busted Ethernet port I can't install from a DVD nor a netinstall CD which would be the easiest options unfortunately. First I tried using the multiple CD option, which seemed promising at first; until I had to swap to the next disk during "configure the package manager". it won't eject the CD when I use the eject key on my keyboard (imac g3 pro keyboard so I go back to the main menu and select the "eject a CD from the drive" option at the near bottom then things seem to get clustered. When I tried inserting the next disk, nothing else will install. It keeps telling me I need disk 1 again through every step. Then at the end, it tells me the installation is complete before I even install a desktop environment from the final CD. Then I just end up booting into garbled text and errors.

After all of that nonsense, I tried making a bootable USB from the DVD ISO with the OS X terminal. This method usually works with just about anything I've done before. However for some reason Debian apparently simply refuses to boot. As I tried selecting it on the boot menu on the start up, it gives me a black screen then goes straight back to the boot screen with disordered graphics. When I tried booting it from open firmware, it goes to the first screen, then when I hit enter to actually boot to the installer, nothing but errors. Finally I tried booting it straight from the ISO file on the hard drive, that method didn't even work at all.

Could someone point out what I'm doing wrong if possible or perhaps recommend me a different option?

I am running Ubuntu 14. in virtual box on a early 2008 imac. I have a shared folder on my imac and have the Ubuntu Public folder shared.

The problem is Ubuntu can not see the imac folder and the imac can not see the Ububtu\Public folder.

Have completely low level formatted hard disk on an old pc created a partion run live cd successfully - puppy precise- and use the install wizard to install to the partition...frugal.
changed the bios to boot from hdd on reboot it seems that it is recognising the os but then a black screen with a flashing dash top left. any ideas?

I clean installed Antergos 64bit (GNOME 3) on my iMac, and now need to boot the OS X DVD that came with the computer to format and restore. The ultimate goal is to keep this machine for dual-booting (which I can take care of) since there are simply things I need from both operating systems. If only Antergos or GRUB would boot from the DVD to kick-off the process.


What have you done so far?

It made sense to install rEFInd on this machine, since that was the program that helped OS X boot the Antergos image from my USB drive in the first place.

I followed the steps laid out in the Arch Wiki. First, by using the refind-install command Then used the refind-install --usedefault /dev/sda1 command to "also install rEFInd to the default/fallback boot path".
I shutdown, and booted the Mac up in hopes to catch rEFInd's splash screen, but to no avail. Only the Antergos/GRUB screen, and then into Antergos as usual.
(This began a hopeless cycle of re-installing, and rebooting which lasted quite some time.)

Afterwards, I tried manually installing rEFInd using the following commands from the Arch Wiki:
Quote:
cp /usr/share/refind/refind_x64.efi $esp/EFI/refind/
efibootmgr -c -d /dev/sda -p 1 -l /EFI/refind/refind_x64.efi -L "rEFInd Boot Manager"
Also, I installed the mactel-boot utility from the AUR.

And according to the efibootmgr utility, rEFInd was now first in the boot order:

Quote:
BootCurrent: 0002
BootOrder: 0004,0003,0002,0080,0001,0000
Boot0000* ubuntu
Boot0001* rEFInd Boot Manager
Boot0002* antergos_grub
Boot0003* rEFInd Boot Manager
Boot0004* rEFInd Boot Manager
Boot0080* Mac OS X
Boot0081* Recovery OS
BootFFFF*
After shutdown/power-on, the machine displayed alot of white-colored "clearing node" text, before tragically booting once again into Antergos/GRUB.

I've also read How-to Geek's guide on re-installing OS X on Mac, yet the tutorial never mentions how to restore it from Linux.


Conclusion:

What piece of this puzzle am I missing? Would creating a LiveUSB of OS X be an easier route than this DVD? Is there a GRUB command I'm not aware of that can change the boot order?

I'm almost certain rEFInd is not the only way Linux would be able to boot this OS X DVD, it's just the only way I've known how so far.

I can clearly see the Mac OS X boot option in efibootmgr as Boot0080*, so at least it's being recognized. When Antergos boots to the desktop, the OS X DVD is displayed as "WindowsSupport" if that helps.
I'm out of my element and am at an impasse, your help will be appreciated.

PLEASE & THANK YOU

I am trying to boot Linux Mint from an 8gb Sandisk USB. I changed my boot settings and it boots into what I believe is called grub? I am given two options, Boot Linux Mint, Boot Linux Mint (compatibility mode). When I select either of them all I get is a black screen. I've tried many things to get around this, messing with my graphics card settings (within grub), different USB's (another 8gb and a 32gb), I tried Ubuntu and that just doesn't boot at all I go straight back to my UEFI settings. I'm very new to Linux and I don't just want to hop in, I just want to boot from my USB whenever I want to play around with it. Thank You

Note: I'm running windows 8.1 currently on a ASUS N550JV laptop. I've been using the UUI from Pen Drive Linux.
