These entries are stored in UEFI’s NVRAM. You could use efibootmgr
on Linux (has to be UEFI-booted) to remove/manage them. This program should be available (either installed by default or from the repositories) on all recent Linux distributions.
Run efibootmgr
as root
to get a list of boot entries:
[root@db-nb-11 ~]# efibootmgr
BootCurrent: 0019
Timeout: 0 seconds
BootOrder: 0019,000C,000A,0006,0007,0008,0009,000B,000E,000F,0010,0011,0012,0013,000D

You might notice that most of these entries aren’t relevant to you. Better take care not to delete anything important, who knows what might happen. ;)
To delete entry Boot0019
, you’d have to execute the following command:
bootmgr --bootnum 19 --delete-bootnum
Or, if you like short options:
bootmgr -b 19 -B

Well, here you go, @foxneZz. – Daniel B – 2015-03-09T18:09:45.683
when I install grub, do I have option to boot windows via boot device selection menu or only through grub? I just forgot to look when I had manjaro. If I fk up my system I would need to find another windows 8 computer or try recovering through liveusb which can be troublesome. Always having option to boot windows through boot menu makes experimenting with linux much easier. I plan to install Arch linux btw :) @Daniel – foxneZz – 2015-03-09T18:22:26.610

Why don't you just use EasyUEFI If you don't have an Windows 8.1 installation disk go ahead and download one from Microsoft using the tool.

I have Win8 iso. But I only have one flash drive. EasyUEFI seems to be exactly what I've been looking for. – foxneZz – 2015-03-09T19:03:27.667
