I installed CentOS 7 yesterday, and grub2 didn't make an entry for Win 7. I then discovered that gparted can't read my NTFS partitions. I've installed ntfs-3g and even *ntfs*.

I've searched here and elsewhere, and everything I found indicated that ntfs-3g should have fixed this problem.

Any suggestions appreciated.

Can you be more specific?

Which commands are you using to read the partitions.
What error messages.
Any error message in the journal?
Also, is Windows shut down or did you just hibernate it?

are you 100 sure that you did not install CentOS7 to the WHOLE disk
that is the default setting


as in

did you use win7 and the tools in win7 to SHRINK the windows partition

leaving it unpartitioned

then installing CentOS 7 to "THAT" unpartitioned space


and install GRUB to the first LINUX partition , leaving win7 to the MBR

cent would than AT the time of install asked you IF you wanted to list "other" as win7

After re-reading my post, I realized that I left out some potentially useful info.

sda is my SSD drive, which contains my Win 7 installation. sdb is my hard drive, which is where I installed CentOS.

Windows will still boot, if I interrupt the boot sequence to tell the BIOS to boot from that drive. If I don't, my default boot order is the hard drive first, so I get the grub2 menu, which contains only CentOS boot options.

I tried running grub2-mkconfig after installing ntfs-3g, but it still doesn't see the Windows partitions on sda. Same with fdisk and blkid. gparted sees the NTFS partitions, but it says it can't read them.

berndbausch: Thanks for responding. I haven't seen any error messages when reading the partition info. I ran journalctl, but didn't see anything that seemed to be related to this problem. Windows was shut down (not hibernated). Please let me know if I can provide more info.

JohnVV: Thanks also for responding. I've tried to answer your questions above; please let me know if I can provide more info.

isn't there like a
this usally picks up what it might have missed in an install or forwhatever reason. Ntfs-3g is for mounting NTFS FS in fstab. from what I know of it, at least that is what I used if for.

if you're getting into your Linux , two me, I install grub(2) on MBR.
it will not hurt it if your re-install grub where ever you put it the first time. or somewhere else, but if you are going to install it somewhere else, I'd unInstall it where ever it is now first, then install it in the somewhere else place next. this is done without rebooting, or loging out then in again , part one then part two right afterwords.

when I had dual boot, I went with MBR, update-grub searches to see if you have other OS's installed and adds them to the conf boot listing file thingy so you can pick one during boot up. it's either install-grub /dev/sdx or grub-install /dev/sdx x being whatever Partition/hdd you want to put it on.

but you knew that didn't you?
