On my computer with dual systems(win7+centos6.4(now 6.5), after I do something, problems came out:
when I plug portable hard disk into my computer, It is not mounted successfully. SO I do as the suggestions from URL 'http://wiki.centos.org/TipsAndTricks/NTFS' with the following block:
_/Installing required packages/_
_//__//__//__//_
_/For /__/*CentOS-6*/__/the /__/*EPEL*/__/repository is carrying later NTFS packages. EPEL is also usable for /__/*CentOS-5*/__/. To install, after enabling the repo per the /__/Repositories http://wiki.centos.org/Repositories/__/page: /__//_
_/yum install ntfs-3g /__//_
_//_
_/or if you prefer to leave EPEL disabled by default /__//_
_/yum --enablerepo epel install ntfs-3g /__//_
_//__//_
_/You may also want to /__//_
_/yum install ntfsprogs ntfsprogs-gnomevfs /__//_
_//_
_/for additional functionality. /__//__//_
_/Mounting an NTFS filesystem/_
_//__//_
_/Suppose your ntfs filesystem is /__//dev/sda1/__/and you are going to mount it on /__//mymnt/win/__/, /__//__/do the following. /__//__//_
_/First, create a mount point. /__//_
_/mkdir /mymnt/win /__//_
_//_
_/Next, /__/*edit*/__//__//etc/fstab/__/as follows. To mount read-only: /__//_
_//dev/sda1 /mymnt/win ntfs-3g ro,umask=0222,defaults 0 0 /__//_
_//_
_/To mount read-write: /__//_
_//dev/sda1 /mymnt/win ntfs-3g rw,umask=0000,defaults 0 0 /__//_
_//_
_/You can now mount it by running: /__//_
_/mount /mymnt/win/_
But after doing that, the error is also reported "Unable to mount location\Error mounting: mount:unknown filesystem type 'ntfs'". So I /*mkdir*/ another */mnt/win*, */delete/* the */mymnt/win* and try again.
the error is reported too!
At the same time, when I reboot the computer. I can not login the Win7 system by error reported " *BOOTMGR is missing*" How can I fix these problem? By the way I use 'fdisk -l' to check my partition and shows as follows:
/Disk /dev/sda: 1000.2 GB, 1000204886016 bytes 255 heads, 63 sectors/track, 121601 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Sector size (logical/physical): 512 bytes / 4096 bytes I/O size (minimum/optimal): 4096 bytes / 4096 bytes Disk identifier: 0x1cc5999d
