1 Drive LVM yes or no, dual boot

[Pat_Foc]

Hi, I wanna try this ubuntu/xubuntu and would perhaps wanna try it as dual boot with windows. I would be only using 1 drive for whole system. I wonder if I should use this LVM during linux installation or not . I know what it does I have been reading about it a little but I wonder if its any good for me, I think mostlikely I wouldnt do much of partition changes... but who knows.

I wanna know if there are any disadvantages (perhaps slower system or such) or not at all and if its only huge plus and helpful tool so there are not any disadvantages why is it optional?

Also if perhaps in the future I'd decide to let windows go off my hard drive and use it all for linux only, could this LVM be any helpful to me with this task? Or in other words, could I get back my disk space that was windows previously using and use all of it for linux only the easy way? Thanks! :)

the easy way is to select a simple installation ;) meaning no lvm

LVM is an additional layer of complexity and therefore an additional opportunity for failure. If you don't know for sure LVM will be good for you, then don't use it. You will be able to resize your partitions or simply reuse them at a later stage, in case you decide to remove Windows. Other people just wipe the entire drive and start afresh, for example when they want to move to the next Ubuntu release. (Re-)Installing isn't too painful in Linux.

LVM is mandatory for fully encrypted systems and may be useful on some servers.

I do not use LVM as it just seems like another level of complication. It was another work around to the 4 primary partition limit with MBR(msdos), but now I only use gpt which does not have that limit.

Windows only boots from gpt with UEFI, but you can use Ubuntu with gpt whether BIOS or UEFI if you have a bios_grub partition for BIOS boot or an efi partition for UEFI boot.l
