Create EFI partition before installing Windows 10

favorite












I'm currently using a dual boot setup on my laptop, with Windows 10 and Fedora and I'm planning to replace my HDD with an SSD for obvious reasons.



I'll make a clean installation of both OS, but I've got a doubt regarding the EFI partition: since Windows creates a 100 mb big ESP by default (if I remember correctly) and that's not enough, I've read that the best way to have a bigger EFI partition is to create it before the installation of Windows 10.



Is that right? Or is there a better way to proceed?

          Most likely, you won't need larger ESP (EFI System Partition). Windows OS loader is rather small and Fedora will most likely just install GRUB on ESP and place the rest of its boot files in /boot which will be on a separate partition anyway. Unless you're going to experiment with unusual Linux setups (like EFISTUB booting etc.), 100 MB should be sufficient.



          If you want to have a larger ESP just in case, you can create one using Windows installation media before the partitioning step.



          How to manually create ESP using Windows installation media



          Before the partitioning step:



          (Technically, you could also do this on the partitioning step and click Refresh afterwards.)




          1. Press Shift+F10 to open Command Line.

          2. Type diskpart Enter. Diskpart will take a while to launch.

          3. Type list disk Enter A list of disks will be printed. Note the number next to yours (most likely 0). Select that disk: select disk 0 Enter.

          4. Create ESP: create partition efi size=500 Enter (500 is partition size in MiB).

          5. Exit Diskpart: exit Enter.

          QoS: MAC-Priority for clients behind a repeater

          Image
          1 1 I've setup a wireless network using a Linksys-Router (DD-WRT) as an AP and a TP-Link repeater for range extension. To manage bandwith for specific users, I've setup QoS-Rules on the AP (DD-WRT) using MAC-Priority: However the AP shows only the Repeater's MAC and the MACs of users inside the AP-Range. The MAC addresses of users behind the Repeater are not listed : The purple MAC is not listed in the AP-Clientlist. Its related to a device connected via the TP-Link repeater. Q: How can I setup MAC-Priority for repeater-clients? Do I simply add the purple MAC in AP-MAC priority list although it's not listed as a client? I want to setup specific priority instead of giving one priority for all clients behind the repeater by adding the repeater's MAC in the MAC priority list in the AP as ...
