I'm going to install Arch Linux on an UEFI computer. I've also Windows 8.1 installed and I would like to keep this operating system in dual boot with Arch. I should ask many questions, because this is the first time I have an UEFI computer with GPT (I have only used the MBR until now.).
My Windows 8.1 system uses these partitions:
OS: normal NTFS partition, Where the OS is installed?
EFI partition (100 MB): The EFI partition created by Windows.
Windows RE (900 MB): I supposed that this is the recovery partition?
Windows RE (20 GB): Why is there an another partition of recovery?
Instead, I've done the partitioning for Arch, with classic
My questions are:
- Suppose I have GRUB UEFI and os-prober: If I format the EFI partition during the Arch installation, will I be able to access it in Windows without any problems? I read that this partition has to be formatted.
- I've also read that I should enlarge this partition to about 200 MB, because I could encounter some problems/mistakes with dual boot. Is this necessary?
- Is there any method to enlarge the partition, without touching other partitions?
- Is it necessary to keep TWO recovery partitions of Windows? If I remove one of these recovery partition, what could happen? I prefer to remove the recovery partition with 20 GB, in my opinion it's only a waste of space.
