No, rEFIt is software and therefore should not affect the hardware warranty. However, if you're concerned about that and want to avoid trouble (there's always the odd thickheaded customer service rep, even at Apple), you can simply wipe your drive and do a clean OS X reinstall before you send your machine in for service (and restore from backup once you get ...

I have done this myself. First install REFIt, an utility for dual/triple booting. It adds a useful selection of OSes on startup. It also includes a EFI/MBR fixing tool which is very useful. You might need to restart 2 times. Using the Disk Utility, add 2 more partitions to your disk. Format them FAT or FAT32. Restart your machine, and this time, assuming you ...

I had the same exact issue with my MacBook Pro and I have rEFInd installed as well. I resolved the problem disabling the autopoweroff option with pmset. See this answer.

Another option: Get a fast external hard drive with a USB 3 or Thunderbolt interface, and install a second instance of Mac OS X on it. Boot from Mac OS X on the external hard drive, and use it to create a BootCamp partition on the external drive, and install Windows 7 or Windows 8 on that. At bootup, with the Option key held down, you could select whether ...

Select Macintosh HD. Hold ⌥ and click on File. Select Disable Journaling. boot from a Linux Live CD. Open root terminal. delete ...

You will need to edit the rEFIt configuration file. Since version 0.14, the configuration file has supported adding a default boot selection, as documented in the news section of the website. However, there isn't very clear documentation on how exactly to do this on rEFIt's website. You could just open the conf file, or view the default on their SVN repo ...

Assuming you have rEFIt installed on one of the partitions on the hard drive, the following steps should remove the delay: Boot via the Mac OS X Install DVD/USB. Launch Terminal (Utilities Menu). Enter diskutil list to list all available disks and partitions. Looking at the list of partitions for "disk0" (internal drive), identify the partition that ...

First install rEFInd, and boot Ubuntu installer after.

If you want to prevent Macbook going from sleep mode into standby mode (dump RAM to SSD) too soon, you could also adjust by changing pmset's standbydelay value. sudo pmset -g to check current setting sudo pmset -a standbydelay [value] to update settting But instead of changing pmset configuration (which affects your battery life), try using the original ...

No. There is no option to change the background to an image, but you can set the color of the background to anything you like. This involves changing the 'banner' image (rEFIt logo by default). The background color will be set to the color of the top-left part of the banner image. Changing your banner image involves changing the rEFIt configuration file. ...

You could install a retail version of Windows on the Mac and migrate your data (which you would previously have backed up) onto it. Just mounting a Windows install that had been made on other hardware is pretty much doomed to failure. The correct hardware drivers won't be present and the existing ones wouldn't be correct for the hardware, for starters.

They are on one of the installation disks that comes with your iMac. Also, I'm pretty sure the drivers get installed if you download and run a "Bootcamp Software Update for Windows" from Apple's support site. They are usually 200MB or up downloads that come packed with drivers for windows, so give it a try in case you can't find your cds.

I suggest that you use BootCamp for Windows 7, and virtualization for Ubuntu. Since Ubuntu requires so fewer system resources than Windows 7 or Mac OS X, your performance hit should be minimal, if noticeable at all. I would first destroy the BootCamp partition using the BootCamp Assistant, then recreate it and install Windows 7. Then install Ubuntu using ...

You'll probably need to redo this setup and install Windows 7 before Ubuntu. I am pretty sure if you install Windows 7 it will take over the GRUB bootloader. There is an article on lifehacker that gives instructions on how to set this up http://lifehac.kr/ihVY4k
