Want to install dual boot OS (Windows 8 & Ubuntu 16.04) on external 2TB Seagate HDD with Non-UEFI (BIOS only supported) by running either Windows 7 OS or Ubuntu 16.04 installed from 4GB USB drive.
Make either 4GB USB drive or Seagate HDD as a bootable disk for all installed OS.
What I have:
- Host machine (Running Windows 7 Ultimate - 32bit - BIOS)
- Seagate external HDD - 2TB (GPT - The Drive, to be install both Windows 8 - 64Bit & Ubuntu 16.04 - 64Bit)
- Sandisk USB drive - 4GB
- Sony USB Drive - 8GB
- Seagate 2TB HDD already has some separate NTFS Partition and formatted using a GPT partition table, want to install OS on that separate partition on the same disk.
- System does not support UEFI (BIOS only)
- System supports boot from USB stick/external HDD
(Host Machine - Windows 7 - BIOS Mode)
- Installed Windows 8 files using "WAIK" (Without boot loader/manager)
- Then installed Ubuntu on the 4GB USB drive (Using Unetbootin)
- Then restarted, and booted from the USB drive and tried to install Ubuntu on another partition on the Seagate drive.
- Then restarted again, but it doesn't detect the bootloader from Seagate disk, instead directly boots to host machine
If we try by installing "windows boot manager" on another 200MB, FAT32 USB drive, then is the host machine must running on the UEFI supported machine..? or is the host machine being in BIOS enough?
(4GB USB Stick - Ubuntu 16.04 - Try Mode)
- Opened "Gparted" tools
- Formatted another "Sony 8GB Pendrive" as, (FAT32, 200MB Partition)
- Install Ubuntu from the same running Ubuntu, except set the Bootloader location as "Sony 8GB" FAT32 partition (No error occurred)
- Restarted, set "Sony Drive" as the first boot drive, but it doesn't detect the boot loader from Sony Disk, instead directly loads to host machine
Please note: * Want only in GPT partition table (No idea how to convert back to BIOS)
Any idea is much appreciated, thanks in advance!
