Hi about creating image and restoring and booting via Usb stick , i have noticed that many devices are added to the uefi (bios) database for example on my friend 's computer , i have seen several devices in the boot menu but not present in the computer (He plugged hard disks , usb sticks and external ssd ) , he does own these devices , he just plugged and after un plugged I thought to disable uefi on in bios , but i guess the laptop will not boot correctly thanks
mantra, You can disable them. You only need 1 entry in Boot Option Priorities... EFI System Partition. If he plugs and unplugs, the entries will come back. But it doesn't matter. Have EFI System Partition as the first entry. If you have BootIt you will use ... BootIt UEFI instead of EFI System Partition.
Brian but do you know why does the uefi bios store every devices like external ssd with only data or usb stick? I can understand boot usb stick but every devices ,it's weird ,should add only bootable with efi he does not own terabyte softwares, i do , but does BootIt UEFI change the bootloader and partitions , doesn't it? do you think BootIt Not UEFI could work on eufi computer ? I mean could be used the mbr thanks
There are 2 BootIt versions. BIBM BM and BootIt UEFI. I'm using the latter version now. BIBM BM doesn't work in a UEFI system. In the past I've had up to ten items in Boot Option Priorities. I disable them and they gradually return. Some BIOSs are worse than others.
hi I would like to know what does the Bios record , I mean the device Id , or the data of efi partition or the efi bootloader data/file but does remove the battery clean up these entries? thanks Brian
Hi Brian sorry for my poor english , is there a working way to avoid these entries? I mean a working way to avoid the bios will store every device in the uefi ? I guess it's not normal add an uefi entry for non bootable device or bootable device mbr with uefi or efi thanks
Hi Brian yes they are Brian in the ventoy threat , you say you keep the CSM in the bios disabled should it work? thanks
mantra, I don't know how to prevent those entries from appearing. They cause no trouble. It's just a cosmetic issue. You can disable the entries but they will probably return. I have noticed if my entries exceed ten then they can't be disabled. My BIOS anyway. This can be corrected by disabling the entries in BootIt UEFI. For example... del uefi bootitem 0x0003 If you have no need to boot legacy devices you can disable CSM. Then your Boot Menu will only be half the size.
Mantra, you are talking about two different things. BIOS/UEFI boot options are different from the Windows Boot menu options. It is difficult to tell from you posts but I think you are asking about the random EFI entries in the boot menu. If this is true then you can remove them easily by following this process Open Command prompt in elevated mode (run as administrator) Type in bcdedit /enum Press Enter It should list all boot menu entries currently available along with their descriptions and unique identifiers. Carefully choose the ones you want to delete by their description entry and then use the following command to delete them by their unique identifiers. (You can just copy paste the long identifiers in command prompt) Type in bcdedit /delete {identifier} Press Enter This will remove the unnecessary EFI entries from your boot menu. Please make a backup before you attempt this just in case. Hopefully this will resolve your issue.
hi @Brian K ok , so CSM enabled is for mbr boot disk ,isn't it? I was sure CSM was for uefi operation system like macos thanks @Raza0007 Hi well good command line but i'm talking about Bios/uefi and not windows boot entries about windows boot entries in past i had only a winpe for creating and restoring images but i like linux based iso , i guess windows can't handle linux based iso like image for linux or R-Drive Image (wonderful program mostly linux based) do they delete bios/Uefi entries? but i need to a windows with uefi partition to remove them? i remember i was able with ubuntu but booting as uefi thanks
Some UEFI entries are baked in with the UEFI firmware and cannot be removed. However, sometimes the UEFI firmware creates NVRAM entries of local devices and then BCDedit syncs them with the BCD data store. These later entries can be deleted. You need to follow the same process with a different first command Type in bcdedit /enum firmware Press Enter Type in bcdedit /delete {identifier} Press Enter You will have to be booted into Windows or booted with WinPE to use these commands. My system is UEFI based and the above commands pull the BCD store from the EFI partition. These commands should work on an MBR system, but I have no way to test it.
