If you find that after pairing your Xbox 360 controller connects and disconnects repeatably after pairing try the following command

echo 1 > /sys/module/bluetooth/parameters/disable_ertm

If this command fixes your your problem you can add the command to /etc/rc.local or add 'bluetooth.disable_ertm=1' to the GRUB_CMDLINE_LINUX line in /etc/default/grub. Then run grub2-mkconfig -o /boot/grub2/grub.cfg and reboot.

Hope this helps, thanks to https://bbs.archlinux.org/viewtopic.php?id=219471 for pointing me in the right direction.

Evidently sometimes Windows 10 will add a partition when upgrading which means grub can't find it's config file.

To fix this you can boot using the Centos 7 install DVD into rescue mode. You need to choose the boot option that matches whatever version of Centos you installed, either legacy boot or EFI,

chroot /mnt/sysimage
(for legacy boot)
grub2-mkconfig -o /boot/grub2/grub.cfg
grub2-install /dev/sda (replace the a with whatever drive is your boot drive)

1. Install the EPEL repository. If you are running Centos 7 you can install EPEL by running yum install epel-release. The package is included in the CentOS Extras repository, enabled by default. If your are running RHEL7 or another variant you can run:

rpm - i https://dl.fedoraproject.org/pub/epel/epel-release-latest-7.noarch.rpm

2. Install the ntfs support modules with yum install ntfs*

3. Mount the Windows drive using either the filemanager or the disks utility

4. run grub2-mkconfig -o /boot/grub2/grub.cfg

You should see a message mentioning that Windows is one of the boot options

There was an error when compiling the vcglib package, access.not in vcglib/wrap/ply/plystuff. All you have to do is add #include <unitstd.h> on a new line after #include <fcntl.h>

Port forwarding mysteriously stopped working on my Dlink DIR825-C1 running DD-WRT. After trying many different things and almost ditching my ISP I found the following solution on http://www.dd-wrt.com/phpBB2/viewtopic.php?p=673373, thanks to user mojud.
