View Full Version : [ubuntu] Dual Boot Windows 7 alongside Ubuntu 14.04 installed on Hybrid HDD

April 1st, 2015, 11:30 AM

This is my first post on this forum. I have recently purchased a Dell Inspiron 15 5548.
http://www.dell.com/my/p/inspiron-15-5548-laptop/pd?oc=w511265myw8&model_id=inspiron-15-5548-laptop The model that I purchased came pre-installed with Ubuntu 14.04. I would like the dual-boot Windows 7 alongside with Ubuntu 14.04 (I don't mind removing the current installation of ubuntu if it is necessary).

Since the Ubuntu was installed on the 8GB Hybrid flash cache on the 1TB HDD, the flash cache is not displayed in my partition table.

prem@prem-dell:~$ sudo parted --list[sudo] password for prem:
Model: ATA ST1000LM014-1EJ1 (scsi)
Disk /dev/sda: 1000GB
Sector size (logical/physical): 512B/4096B
Partition Table: gpt

Number Start End Size File system Name Flags
1 1049kB 525MB 524MB fat32 EFI system partition boot
2 525MB 567MB 41.9MB fat32 Basic data partition hidden
3 567MB 3789MB 3221MB fat32 Basic data partition msftdata
4 3789MB 983GB 979GB ext4
5 983GB 1000GB 17.0GB linux-swap(v1)

I have been searching for a tutorial on how to install Windows along-side Ubuntu but was only able to find the reverse.

Please advise.

Thanks in advance.

The output you posted from the parted command shows a Linux partition (ext4 filesystem) of 979GB which is almost the entire drive. First use GParted do shrink that partition to make room for windows. You also have an EFI partition so I would expect Ubuntu is installed in EFI mode so you need to install windows 7 EFI also. Or you could change to MBR and install windows 7 in MBR and then if you want to install Ubuntu, install it also in MBR. Have you tried booting your windows 7 media yet and if so, what happens?

Windows expects certain partitions, so best to let it create partitions in unallocated space.
Microsoft suggested partitions including reserved partition for gpt & UEFI:
Order on drive is important: msftres

You cannot use the Win7 DVD in UEFI mode, you need to use BIOS mode or modify to USB with UEFI.
Convert Windows BIOS to UEFI - Also command line install of files to efi partition uses rufus

Only 64 bit supported for UEFI boot
Prepare an usb thumb drive, to boot windows 7 in UEFI mode

Thanks yancek and oldfred. I will try it out and let you know.

oldfred: I would like to know, given the circumstances that i made a mistake and would like to re-create the partition table, how would I set the ubuntu to install into the 8GB flash cache?

Is Ubuntu / (root) in cache? That is pretty small for /. I normally have 25GB allocated to / and use about 11GB of that including about 2GB for /home. But do have all data on hard drive.

I would full document system with Boot-Repair's Summary report. And save a copy of that to another device, DVD or flash drive. Then you know exactly how system is configured. Not sure the link to the paste bin last for more than a few months, so make sure you have a copy somewhere.

Boot Repair -Also handles LVM, GPT, separate /boot and UEFI dual boot.:
Precise, Trusty, Vivid, & Utopic all should work now with current ppa

You should have current version repair tools for all installed systems. The installer for Ubuntu or repair CD/flash drive for Windows. You can add Boot-Repair easily to the Ubuntu installer.
