    Hello,
    I'm not really sure where to post this, I have an hp pc that came with win8 preinstalled.
    I needed ubuntu to do some stuff with android but I couldn't figure out how to dual boot win8 and ubuntu, so I deleted windows 8 and installed ubuntu. I later realized I needed windows for other things so I grabbed a win7 iso and installed it,
    figuring i could dual boot without issue, but when I try to install ubuntu it tells me i have no os installed and gives me no option create partition. I'm not very knowledgeable when it comes to pc's, I know just enough to get by. Any help you guys can offer would be greatly appreciated, Thanks

    I have found, as this is long winded but definatly the best way ( in my opinion :biggrin: ) doing any dual boot is......

    Have each OS on it's own drive.

    You want Win 8. Have one HDD in and install Win 8 onto that drive.
    Remove that drive.
    On a separate drive install your second OS, Linux.
    Connect both drives back into the PC.
    Select which OS you want as your main OS. Set that in the BIOS as default first boot.
    So when the PC is switched on it will start that OS automaticly.
    To boot up into the other OS ( in my case F8 ) Press F8 at post bringing up the boot manager allowing to select manually the second OS.
    This boots up nicely. You use it for what you need.
    Your PC gets turned off but the next time it is turned on up boots your main OS..

    NO bother. No messy boot problems.

    Just a bit long winded to set up in the first place...That's how I do it, that's how I always recommend anybody to do it.

    To be honest I think everybody should have at least one spare drive, damn I have 8 of the things lying about..:eek:

    Well this is why...

    once you have partitioned your drive, installed each of the OS's and got EasyBCD set up, don't take too long to set it up..

    At post you are left with a boot screen to select which OS you want to boot into. You can set the default OS, you can set the amount of time you want to allow yourself to select which OS you want.

    I just don't want that. I hate it.....It's like when you install, say Win 7. then you install a fresh Win onto the same drive but at the install you don't delete all the partitions and volumes then make new ones, you just format an install. At post you get a choice of which Win 7 to boot into even though there is only one...

    KAK.....

    I hope you do like it. I hope it works for you.:biggrin:

    I, I, I just don't....:(

    Mmmmmmm, I know I keep saying I don't like that tool but I have used it and it has worked in the past.

    Can you go into detail of how your installing the OS's.
    Which one first.
    Is the drive GPT or MBR ( not sure if this can cause a problem )

    How have you partitioned the drive ?

    Later on if I find some spare time I may have a go myself on my test rig and see what's happening.
    It has been a while since I messed with Easybcd.

    Maybe somebody in the know will cast a light here ?

    Just to confirm, dual boot Win 7 and Ubuntu.

    Will have to download the latest one.

    Right I have some free time this arfo.

    I have downloaded the latest uBunto 13.10 x64.

    What I am doing is :-

    On my test rig an LGA 1155 PC with one 80 gig hard drive installed. I am going to install Win 7 x64.
    I will make note of the steps I will take.
    I will use DISKPART to create two partitions on the one hard drive.
    I will install Win 7.
    I will make sure Win 7 boots up and runs nicely.
    I will then attempt to install Ubuntu onto the same hard drive using the second partition.
    I will test if Ubuntu boots up and runs nicely.
    I will test to see if it is possible to boot into either without any 3rd party tools.

    I will report back with my findings and notes.

    gives me summet to do...:cool:

    Hi..

    Well I have tested installing Win 7 and Ubuntu. It all went well.

    I will test my notes one more time then post them here. EsyBCD was needed ! It is FREE to download. I gave false name and email addy.

    NB..Changed it slightly, no need for DISKPART. I read through your initial post, don't want to confuse you too much..

    All the partitioning can be done using the Win 7 and Ubuntu installers.

    I'm installing windows first, and my drive is MBR. I partitioned with GParted.
    With easyBCD i selected the option to let it install grub, and in the other section I
    clicked browse, and selected my iso and clicked "add entry" It foze and said not responding
    but I let it keep going. When it started responding it didnt do anything, but i saw linux mint
    in the edit boot menu list. i restarted my computer and selected it and got an error
    (dont remember what it said) but I erased hd again, going to keep trying till I get it

    2 things might be slightly wrong..
    1: MBR of win7 to be written in Easybcd deploy button.. write 7 mbr.
    2: Grub legacy ? i use Grub2 . auto finds it

    These are Easybcd options.

    I appologise if my Easybcd settings are not quite right. It has been quite some years since I last used it and kept things mainly default.

    If the above settings work for the OP that is great.

    Thanks LatinMcG :cool:

    Thanks for all your help.

    Having secure boot non-existed, HD partition mbr not gpt helps. found dual booting better than dealing with hyper-v's "choppy" feel, the nicest way of describing!

    I have a laptop preinstalled w/ win 8, upgraded to 8.1. In computer management shrunk HD, a 40g size left unpartitioned. Created a boot usb for backbox (Ubuntu based OS meant for exploitation, reverse engineering, Gray hat hacking etc.) Booted usb in live mode, created ext4/swap partion with 40g free space for backbox install. Downloaded grub customizer in backbox, set win 8.1 as primary os. to boot into backbox I just press the down arrow before windows starts loading. Easy Peasy. Note, I named both OS the same, so I am able to reserve my IP,mac address, port forwarding, vpn etc. in router with less worries. router doesn't care about OS being used!
