I am installing scientific linux 6.9 (based on redhat 6) on my surface book . I created 4 partition :

88500MB / ext4
500MB /boot/efi EFI system partitioning
250MB /boot ext4
200MB swap

But when i click next i got the error : you haven't created /boot/efi partition. How can i solve this problem ?

  • The ESP (EFI System Partition) should be a small FAT32 formatted partition preferably at the very beginning of the drive (/EFI, not /boot/efi). With manula partitioning make sure to select all required partitions including the ESP. The3 installer will do everything else for you. – user252181 Feb 28 '18 at 10:55
  • @ MichaelBay tanks alot. but I didn't understand . You mean I wrote /EFI instead of /boot/efi. May you give more explanation? – Fatemeh Moh Feb 28 '18 at 12:19

As MichaelBay mentioned, your EFI partition needs to be formatted with FAT32. However, I understand that the way it's mounted can be confusing. Especially since it can be distro-specific.

According to RedHat's documentation, the EFI filesystem should be mounted at /boot/efi/EFI. This means that:

  1. You need a FAT32-formatted partition of type EF00.
  2. The partition must be configured to be mounted at /boot/efi
  3. The filesystem in the partition must have an EFI directory.

In other words, your root filesystem will contain the directory /boot/efi, your ESP partition will contain the directory EFI, and the ESP partition will be mounted at /boot/efi, resulting in the path /boot/efi/EFI.

You can use the following layout in the installer:

88500MB / ext4
500MB /boot/efi fat32, but make sure the partition type is ESP/FE00.
200MB swap
