# Ubuntu – Can’t install Ubuntu on Windows partition

The following is the disk management screenshot of windows:

I want to install the ubuntu on the partition: New Volume (F:)

I made the pen-drive bootable by Rufus with Ubuntu 16.04; While rebooting the PC and trying to install the ubuntu, following information is shown:

sda1: 1MB windows 7
sda2: 104MB unknown (ntfs)
sda3: 105GB (used: 60GB) (ntfs)
sda4: 207GB (used: 48GB) (ntfs)


How do I proceed with the installation? My aim was to install on the partition: New Volume (F:).

Also note that install alongside windows option is not visible, with both unallocated space on the disk and allocated space on the disk.

The reason for this is that, even when you remove the partition you created for Ubuntu, you'll have four partitions. The reason the Windows tools use dynamic disks when you go above that number is that MBR supports a maximum of four primary partitions. Most OSes use logical partitions to go beyond the 4-primary-partition limit, but these require the presence of a special type of primary partition known as an extended partition. If you delete the to-be-Ubuntu partition and then convert to basic form, the tool is likely to turn all four of your partitions into primary partitions, leaving no room for the extended partition Ubuntu will need. If you can convert all five partitions, though, the conversion tool should create an extended partition and convert two partitions (probably your E: and the to-be-Ubuntu partition) into logical partitions. If the conversion tool refuses to convert more than four partitions, you can delete the to-be-Ubuntu partition, convert the remaining four partitions, and use my FixParts program to convert the final primary partition to logical form; however, you may need to use something else to slightly resize the partition that comes before the to-be-logical partition to make room for the extra data structures that logical partitions require.
