Problem installing Windows 10 - 4 partitions already created
Hi everybody. I am really satisfied with my Dell Inspiron 14 7000 (7437). I would really like to try the new Windows 10, and I would like to install it in dual-boot with my current Windows 8.1
Unfortunately, it seems impossible. I created a new partition, shrinking the main one. When I choose the new partition, Windows 10 won't install in it, due to the GPT format. I used Rufus to create a GPT USB with Windows 10.
Looking around the problem seems to be the limit of 4 primary partition on GPT disk, already reached due to Dell partition. Can I delete one of them? Is there a solution?

Make sure you make Windows 8.1 with Update 1 installation media so you can revert to Windows 8.1 if you need:

Likely your recovery partition is non-functional now that you've resized partitions on the drive.
I installed Windows 10 9926 on my Inspiron 13 7347. I never tried a dual boot however and wouldn't advise doing so. See here for installing Windows 10:

Wow, you're a genius! Now it works really good!
Just a problem: the system seems not to use the SSD chache anymore: I installed Intel Smart Response, and tried to change AHCI in Intel Smart reponse technology, but I had to give the priority to Windows 8.1. However, the system is still slow(er) and from the Task Manager, I can see the Disco 0 (HDD) is used 100%, while Disco 1 (SSD) 0%. And I feel the system slower, especially at start-up.
Is it normal? Any solution?

"The SATA operation needs to be at Intel Rapid Response Technology before Windows installation for it to work."
But in this video https://www.youtube.com/watch?v=IGJ4MnZTNXo&index=2&list=PL1RkaknDn7v_SJaBuleIyodZD7Nt_IgqM you suggested to change the SATA operation AHCI; I'm sorry if I misunderstood something.
Still now, Windows 10 will not work with "Intel Smart responde technology" set from BIOS. I can imagine how it could be difficult to make everything work.

I can see there being even more problems if you are trying to use a Cache Drive with a dual boot. The Cache Drives sometimes have issues with just a single Operating System.
The SATA operation needs to be at Intel Rapid Response Technology before Windows installation for it to work. As mentioned its probably not going to work well with a dual boot.
Try this at your own risk - it may result in a non-bootable Windows 8.1 Install
Change the SATA operation to AHCI and booting with Windows 8.1 with Update 1 installation media. Use DiskPart to clean the SSD:

After cleaning is done, revert the SATA operation back to Intel Rapid Response Technology. Then boot up Windows 8.1 Then try to use the Intel Smart Response program to cache the SSD.
