At the moment I already have installed windows 7. When I cut off the memory from the disk d and attached it to the disk with Acronis Disk Director from Windows, not from the BIOS. Once everything went well, but there was a case when the acronis flew with an error, and I could hardly somehow recover the disk without formatting and the system started up normally.

Now I need to install Ubuntu Linux next to the already installed Windows. I have a disk, almost empty - sda1, by all logic there should be a system partition, but I have a C drive located on sda2. And the D drive is somehow in the extended shell.

If I try to cut a piece from sda1 and create an extension for linux there, an error will crash: enter image description here

Question: how can I correctly mark up (it is possible to correct this curve markup) without consequences for Windows and correctly install Linux?

    From experience, I can say the following: how to treat this is easier to give birth to a new one. Pererazme all anew (think up - I can tell more or less the best option). You can move the partitions of course, but then the Windows may pop up with an error about winload.exe . And so @LebedevAleksey told why an error occurs on the screen. - don Rumata
  • @donRumata is there an option to remap without damaging the files and generally loading Windows? - Valeriy Posvistak

    Yes, but still it is better to backup important files to a separate physical disk. - don Rumata

You have already created 4 main partitions sda1, sda2, sda4, sda5 that is the maximum number of main partitions, then you can create only additional partitions (extended). You can create an extended sda5 partition for Linux. You can put the system in the extended partition, only the bootloader should be in the primary partition. Format the sda1 partition and put the GRUB boot loader in the settings and tell it that you have two Windows systems in sda2 and Linux in sda5.

  • By the way, I tried to format this almost empty disk on Windows, pops up "Windows unable to complete the format" - Valeriy Posvistak

    You first need to create a partition there and as I said it should be an extendex partition. I also advise you to create a new disk structure and reinstall everything. For example: sda1 - the main partition with the loader. sda2 - the main partition with windows. sda3 - swap partition for linux sda4 - main linux partition. Then you can create extended partitions for data. - Lebedev Aleksey
  • Okay, but how can I remove the existing extended, while leaving a logical partition, from which I otpil somewhere 50 GB, and from them do extended? - Valeriy Posvistak
  • You can format directly from under Windows and assign partitions - partitionwizard.com - avparfiriev
  • @avparfiriev formatted the acronym from under Windows and regretted it - Valeriy Posvistak

The problem was solved by adding new logical partitions to the existing extended partition (sawed off from Local Disk D)
