Linux itself and most Linux bootloaders don't care about the type of partition that Linux is installed it, and don't care whether the partition is marked active. Marking a partition as active is mostly necessary for bootloaders that are installed in the MBR and chainload a bootloader from a partition. Windows's bootloader requires an active partition (or at ...

You might be interested in Rod's EFI bootloaders introduction and my ALT Linux Rescue might come handy as it contains both Refind boot manager and all the tools needed to mess with partitions and filesystems (e.g., to create another ESP if debian installer didn't do that for you). Note that ESP -- a FAT32 partition with a special GPT UUID -- is both ...

Why would you need 3 partitions? You only need one. Either sda2 or sda3 are big enough for a normal installation.

I did have to go into the BIOS settings of the PC and enable "Virtualization Features" before the machine allowed CentOS 7 to install. There were problems involved in the dual boot ...

Part 1 Download Refind, and see the question I asked recently dealing with some of the issues you'll face. Assuming you're using Windows 8.1, you'll want to use the Refind CD-R Image. Be sure to extract the ISO from the zip file, and mount it in Windows 8.1. Note: You need not burn the image as Windows 8.1 supports mounting ISO files now like Linux has ...

The issue here is that GRUB cannot detect windows installed on your system. However, the GRUB on your flash drive can. In order to fix this, download any recent Ubuntu live medium, then mount the flash drive and hard drive. Now, take a look at the GRUB config file on your flash drive and copy it to your hard drive's GRUB. Make sure you change the values to ...

Following up on the answer by @terdon - when you do the test-step, and grub2-mkconfig does not find the Windows partition. Next, make sure you have the "ntfs-3g" package installed, so that your Linux system can read the Windows partition(s). sudo yum install ntfs-3g After installing that, when you run sudo grub2-mkconfig > /dev/null ... you ...
