Dual Boot Windows / CentOS7 Problem

I have a Toshiba Laptop that had a Dual Boot of Windows 7 and Linux Mint 17 on it and both OS's worked fine. I've been wanting to use CentOS 7 as my primary OS so that I can become more familar with RPM management and proceeded to remove my Mint installation and replace it with the CENTOS 7 installation, and the install completed successfully. HOWEVER, here's my problem.....

When my laptop starts up, I don't see GRUB nor do I have any option of selecting whether to run Windows or CentOS. It automatically loads up Centos 7. When I do a 'sudo fdisk -l', I can see that SDA1 is an NTFS drive, and when I try the following 'sudo mount /dev/sda1 /media/Main\ Drive' I get an error message saying that I can't mount an NTFS drive.

Am I missing something or is there a way to access my Windows files from within Centos. I was able to do this with Mint without an issue, but unable to see any of my windows drives because I can't mount an NTFS drive.

I have no problem with keeping CENTOS as my only OS on this laptop, however, I do need to access the files from the Window's partition, and if anyone can help me to access my files, that would be totally awesome.

Thank you in advance for reading through this and for any help offered.....

Dual Boot Centos7 And Kali

I had Kali and Linux Mint installed and erased Mint to install Centos7. Grub was totally deleted and I could only boot into grub recovery. Many hours of cussing later I got Kali back, I can see Centos filesystem mounted on my desktop and in disk utility. I never finished setting Centos up as I was rushed out the door which probably caused the problem in the first place, for some reason it's raid and although it's 2 harddrives they are not set up for raid and 1 is Kali and 1 is Centos. The Centos boot folder is still empty after running grub-install on it twice and it does not show in grub. How do I get Centos as an option?

I Set Up An Ext4 Partition On External HD To Store Media Files. Permission Issues

I recently bought a WD external hard drive for storing file of several types. Using gparted I made two partitions, one ntfs for windows files and an ext 4 for linux files. Strangely, I have complete access to ntfs partition from linux side of duel boot system, but do not have permission to access ext4 partition. My root password does not work when I use su to gain root access. It works fine on built in hard drive.

Delete MBR File From BCD

Did it again!

Last week, with help from this forum, I was able to install Linux Mint 17.1 dual boot with Windows 8.1. It worked so well, I decided to explore other Linux distros recommended by forum members as some I wanted to check out.

I was using Unetbootin to download and install these as live sessions on my Windows 8.1 partition.

On my last such download, something went wrong, and no doubt I caused the error, but no clue as to how.

When I opened up this PC, I got the normal dual boot option for Windows and Mint. When I selected Windows, I found an additional dual boot option between it and Unetbootin! Somehow I created a partition (?) on my C Drive for Unetbootin (see Thumbnail below).
This Unetbootin option only goes to a page for me to choose another OS. Further, when I rebooted, the Windows/Mint dual boot option no longer existed, just the Windows/Unetbootin one.

Been checking out various articles and websites about BCD/MBR repair, but nothing definitive (that I can understand) about modifying these to delete the Unetbootin partition and restoring the Windows/linux dual boot.

Naturally, this is a newbie land mine area, so I'm very reluctant to try anything I can't fully understand, which is the category everything I've Googled on this topic falls into.

Anyone know how I can resolve this short of a complete start over
installation based on steps that basically a PC fence post can follow?

TIA
Cheers!

Need Help Uninstalling Mint 17.1 To Do A Clean Installation Dual Boot With Win 8.1

Hello All. This is my first post here. I am worse than a newbie; I'm a PC dinosaur! Not joking either.
Recently got a Dell Inspiron 3048 with Windows 8.1 pre installed. As I am a die hard XP user (my other PC is a Dell Dimension 2400), and seeing that PC's days may be numbered, I want to start using Linux, and decided Mint 17.1 would be first on the list.
Ordered a Linux Mint 17.1 boot disk and went to install it. At the option for a dual boot with Windows, I got lost, and did not understand the "other" choice versus making Linux the only OS on the PC. I wound up wiping my HDD and lost contact with Windows 8.1. Fortunately, the Dell Tech I got at Dell Support was able to walk me through getting Windows back up, but the only way I can now access Mint 17.1 is with the boot disk, but there is no set up options as it is already set up, even though incorrectly for a dual boot.
How do I wipe out Linux without losing Windows 8.1 as well so I can re install Linux and this time make the correct selection for a dual boot?
Anyone willing to respond please do so small and slow so I can follow.
TIA.
BTW, I have tried installing Zorin OS 9 Ultimate on my XP machine via DVD and USB, but I can't get past the f1/f2 loop, even though I have reconfigured my boot sequence according to the drive I'm installing from. Zorin support has been MIA on this. Anyone having a similar problem?
Cheers

Cant See Windows Option

Since then I cant find Windows entry in the Grub.

Trying To Install Dual-Boot With AVLinux And Windows XP

I've made a couple attempts at installing these OS's on my machine and am still not getting it. I've actually been using AVLinux for about the past nine months, and it's working fairly well. And, yes, I know XP is down for the count, but for the moment it's the only MS option available to me - and I *need* to get it running for some work related web stuff...

This is all on a 32 bit AMD system btw.

What I've tried: Everything on one SATA drive. Partition one formatted to NTFS (about 20GB) for XP. Partitions 2 and 3 are Root and Home for AVLinux, Partition 4 at the end of the drive as the /swap for AVL.

All the how-to's and guides I've been able to come across point to (usually) Mint or Ubuntu's install dialog, and to select "something else" - which, by the way, is not a function of AVLinux's installation procedure. During install you can install GRUB to the MBR *or* root partition..

So, just to clarify to procedure (as I might have it now, but am very unsure) XP gets installed first (which is done at this point...) then my Linux distro *to the MBR* (?) then I need to add a stanza to GRUB telling it where XP lives? XP is not showing up on GRUB as I'm doing it, but I'm not too sure if installing Linux to the MBR (on the same physical drive as XP) actually wipes out the Windows bootloader....and if so, how chainloading would actually work...

So, any help appreciated, thanks.
