Hi,

 

I'm running windows 7 and would like to dualboot Linux Mint. I have a single HDD with 5 partitions.

 

This is what I see from my win7:

Attached File  win.jpg   32.06KB   0 downloads

 

This is what I see when I load Mint from the liveboot (i've marked the partitions as seen from win7):

Attached File  mint inside.jpg   65.25KB   0 downloads

 

However, when I try to install Mint, I get this:

Attached File  mint inst.jpg   59.43KB   0 downloads

 

From the size, I believe the sda3 in the above picture is my C drive and sda4 refers to the rest of my drives. i.e.,D, E and L. 

 

I'd like to know how to install Mint in my L drive, leaving D and E drives alone. 

I prefer to split this L into 3 for Mint's Root, Swap and Home.

 

BTW, I'm following this guide:https://itsfoss.com/guide-install-linux-mint-16-dual-boot-windows/

 

Thanks for any response.

I can't tell much of that myself, the pics aren't very good.  Can you count how many Primary drives you have?  It looks like you already have Four, and Four is the limit on an MBR Partition Table.  One of the Four will have to be sacrificed to Create a Extended Partition, then you can Re-Create more "Logical" Partitions to Replace and install Linux on.  You need to know what exactly is on the Partition that you intend to sacrifice, that way you can back that info up before the process.  Like, are they Recovery Drive, OEM Tool partitions etc.
 
"MBR also only supports up to four primary partitions — if you want more, you have to make one of your primary partitions an “extended partition” and create logical partitions inside it."[/size]

Since this is a Linux Forum it may be best to get some info from your Linux Mint LinuxLiveSession Media while you are booted into it.  If you have time please Copy Paste this Command in the Terminal and post the outcome here.  First we might as well get your system specs.  Click on the Menu and type "Terminal", when you see it come up click on it to open.  It will look like the Windows CMD.

inxi -Fxz 

Then, so we can take a look at your Partition Information do the same with this:

sudo parted -l

Hi,

No need for guerrilla style screenshots in windows, its not windows xp anymore

 

How to take screenshots with linux mint:

Mint 18 has its own screenshot tool, its in the menus called "screenshot"

Hi,

Yes, the next step is to reduce the number of partitions from 4 to 3. Then in the newly unallocated space, create an extended partition, and within the extended partition you can create multiple logical partitions, as pcpunk mentioned.

I don't have time to assist, but I have been lurking, and would suggest you provide a Diskpart output. It may help people address the issue of 3 partitions being detected as 1.

Share A Diskpart Output:
1. Boot Windows 7.
2. Open the Command Prompt.
3. Type:

diskpart

4. In the new Command Prompt, wait until "DISKPART>" appears, then type:

select disk 0

5. Type:

list partition

6. Highlight the output using your mouse, and press "control" + "c" to copy it to the clipboard. Then paste it into
this thread.
7. Type:

exit

8. Close the Command Prompt.
 

Don't attempt to install Linux Mint until this issue has been addressed.
