Missing OS

Hi,
I'm new to Linux and Porteus. I tried installing Porteus KDE to my 128gb USB to use as a portable second drive.
I tried copying the files and running the windows installer and I've created a live USB and installed from there. The Live usb runs fine.
When I shut down the pc, and plugged in only the 128gb usb I got a Missing Operating system bios error. I tried changing the CSM settings, but I'm not sure what those should be. Maybe a bootloader issue?
I tried installing to another USB and booting up from another PC.
I tried installing Kubuntu a and KDE Neon before, the live usb works fine, but after the install is done (if the errors I got could be resolved), at the next boot it shows an unusably laggy login screen, then not much else after entering the password.
I have an Asus motherboard, i7-3770, 32gb ram, ROG1070 GPU.
What am I doing wrong?
and keep in mind that I'm 15 and not a native English speaker, so you may have to simplify things.
thanks, If anyone can help.

Hello aronkvh, welcome to Porteus.

You said you had a harddrive, what OS is on it? Windows? What did you use to boot the USB drive, a boot manager like grub or grub4dos or the netbook's bios options?

Hi,
I have windwos installed on my main ssd, and I booted from BIOS

Ok, what I recommend is you install Grub2Win on the Windows system. It's what I use to boot multiple systems. Install it, run it, and build a menu entry to boot the USB system. Something like this should work:

Code: Select all

   set bootdrv=$root
   search -f  /porteus/porteus-v4.0-i586.cfg  --set=root    # tweak file name to match your USB system's file 
   if [ $root != $bootdrv ]; then
      linux  /boot/syslinux/vmlinuz 
      initrd /boot/syslinux/initrd.xz
   else
     echo "----------------------------------------"
     echo Porteus drive NOT found.
     echo
     sleep -v -i 10
  fi
  set root=$bootdrv
Then reboot.
