Unable to create partition for dual boot

Post by foureyes28 » Tue Feb 06, 2018 5:57 pm

We are attempting to install Linux Mint 18.2 Cinnamon in a dual boot configuration with Windows 7. We have tried creating partitions both with the windows partition manager and gparted. The installation program doesn't seem to be able to see the partitions we have created. Would you like to see screen shots of the three applications (windows partition manager, gparted, and mint installation? We are two programmers (once upon a time) and totally stumped. Please help?

Hello foureyes28 Image

Welcome to Linux Mint and the Linux Mint forum :)

That would certainly help.

Also open the terminal and paste back sudo blkid and sudo fdisk -l

If the size of the screenshots are too large to attach here then you'll have to use a photo site and supply the link here.

A lot of members use https://imgur.com/upload for this.

One thing that's really confusing is fdisk showing 4 partitions for /sda and blkid showing 5.

Four is the maximum for mdsos primary partitions :?

Hi Again Wharfrat! (Have a friend named 'Wilfred', it's almost like Wharfrat!)

Here's the link for the screenshots.

So, that may be the problem, there are too many partitions. This is a used computer, with windows already installed, and I think it had more than four to start with, and we just added at least one... or two... no wonder the mint installer can't see them?

We really don't want to delete windoze... guess maybe we need to start combining partitions? Have to admit I was never a very good programmer, and probably an absolute zero as a sysadmin...

That's definitely the problem, you're maxed-out with primary partitions

Try deleting /dev/sda3: LABEL="FORLINUX" UUID="3E40F05340F0137F" TYPE="ntfs" as I'm guessing that's the one you would want for linux and create an extended partition
then logical partitions within the extended.

UPDATE: On second look the installation is seeing /dev/sda3

What you won't be able to create is a swap partition.

UPDATE -- We were unsuccessful...

Post by foureyes28 » Sat Feb 10, 2018 1:23 pm

We messed around with the partitions, probably not doing things all that sensible -- broke windoze, decided to install linux mint only, which we are doing now, and we really like linux, so it's not such a tragedy. Think me may try running windoze from a virtual box... wonder if there is a thread for that on here?
