Windows 7: Dual Boot Windows 7 Linux: Partitioning with Linux disk tools problem

Dual Boot Windows 7 Linux: Partitioning with Linux disk tools problem

Goal: Dual boot Windows 7 and Linux and have an NTFS partition for both OS.

Problem: When creating Logical Partitions with any Linux partition tool(Gparted, cfdisk) the Linux swap and ext 4 partitions shows up on Windows 7 as primary partitions outside of the Extended partition while the NTFS partition shows up inside the Extended partition as logical drive. Disk management shows 5 primary partitions and 1 logical drive inside an extended partition.(As seen in Disk1.jpg attachment) I'm using MBR.(not UEFI)

I can create the partitions in Windows 7 disk management and choose not to format the two logical partitions used for Linux. I can then use the mkswap and mkfs.ext4 command to format the partitions.(See Disk2.jpg attachment)

Why is Windows 7 disk management not showing my partitions correctly when I use a Linux tool to partition the disk? Will this cause any problems with Windows 7? I'm afraid of making Windows 7 unbootable.(although it booted just fine I do plan on using EasyBCD to add an entry to load the grub bootloader for Linux)

If I partition my disk with Windows 7 disk management(as seen in Disk2.jpg) will that cause any problems for Linux?

What is the recommended way to handle this? What are the downsides to each way?

Note: I'm a bit of a linux noob.

Hi and welcome to SevenForums,
I never had luck installing Linux in dual boot win-7 when have the 100mb system reserved partition
Seems Linux can not take control of the boot loader unless it's on the C drive with windows

Another problem is you have a 15gb partition in front of the 100mb partition too :/

Personally if you really want to do a dual boot you'll need to integrate the 100mb partition onto C drive
System Reserved Partition - Delete
Easier to do with a clean install just don't create any install partitions to install win-7 on and also do not have any partitions at all until after 7 is installed.

Thank you for your reply. :)

The 15 GB partition at the front is the Samsung Recovery partition for my N150 netbook.

Reading that guide it says I need to delete the System Reserved partition while also stating it's not recommended if I want to hold on to OEM recovery solutions which I do.

Where do you encounter problems if trying to dualboot with 100 MB partition? Is it something to do with EasyBCD? I want to give it a go anyways and see what happens as long as I don't break the current Samsung recovery/Win 7 configuration. I want to use the Win 7 bootloader and chainload into grub2 for Linux.

What is your opinion of Disk management showing 5 primary partitions despite any linux partitioning tool showing the correct configuration of 3 primary partitions and an extended partition(with 3 logical partitions). Will that cause problems for Windows?

Well the problem I had was it just didn't work
The only option Linux gave was install along side of 7
Not at all the same thing
And I thought that was just too freaking cozy of a relationship with windows seeing viruses..... might not effect Linux but do indeed effect windows and there isn't even a separating partition for the two :/

So ultimately what I did was use a dual ssd ez swap instead and installed Linux on it's own ssd
Now I just shutdown and swap out ssd's
7 on it's own and Linux on it's own

Just wanted to give an update.

Even though Disk management shows the disks incorrectly(disk1.jpg) if you go into cmd.exe and run the diskpart utility and enter the command:

list partition
It will show the disks correctly.

I managed to dual boot Linux and windows 7 successfully while keeping the partitions as shown in disk1.jpg. I just installed grub onto the Linux partition instead of the MBR. I then used EasyBCD to add an entry for the Linux partition. So basically I chainload into grub. System recovery partition from Samsung works too.

I did not use an automated installer. I installed from commandline. I'm running Arch Linux. I hope this helps someone!

Thanks for the update :)
Yea grub well from what I've read grub is very difficult to get rid of = I don't know that for sure but I have not dual booted on the same drive again since installing along side as I describe earlier
I very much prefer on separate drives for each os they play with each other so much nicer
