I'm also facing a boot problem.
This is my FIRST attempt at Ubuntu, and I've very little knowledge about it.
I just installed Ubuntu 12.04 alongside with Windows 7.
I had downloaded Ubuntu 12.04 and saved it to a DVD after which I installed it.
I selected the ext4 file system and the mount point as '/'.
I selected the 20000MB free space from the disk for installing Ubuntu.
I DID NOT however give a swap space.
The entire installation is complete and I've removed the DVD.
But when I restarted my laptop, the boot menu shows only Windows 7 and does not show Ubuntu.
When I searched the internet, I found out that my MBR (Master Boot Record) must have some wrong settings. But I am not sure how to manually edit the boot and am also unaware of the commands.
What can I do now?
P.S. I'm using a Dell Inspiron1525 laptop with 2 GB RAM and 250 GB of HDD.
MBR is not my thing , so i do almost everything from partitioning to allocating space manually .. below are the steps ..
1) Install windows 7 (with minimum 4 drives .. C drive(8 to 10 gb) in which Win7 is allocated ... D (ur data) .. E (ur data)...F (empty) ... well we are installing ubuntu in last drive so i said F empty .. by the way you can keep D or E empty too)
2) Insert ubuntu disk
3) Once installation starts it will ask i) Install Linux alongwith Windows ii) Replace Windows with Linux iii)Something else
4) Click "something else" & press forward button
5) After that you will see hard disk partition. I installed ubuntu in my Fourth partition (Disk0 Partition4)
6) First press "add" button .. you will see create partition box in that go to mount point place ... select
/boot give 2000MB (depends upon your drive space availability) .. same as do for
/home 2000MB,
/tem 2000MB,
/user 8000MB (More the user space it will be better),
/var 2000MB,
/srv 2000MB,
/opt 2000MB &
/usr/local 2000MB.
Now very important step
7)How to give "
SWAP AREA" ...For that go in "
Use as" - place by default you will see "
Ext4 journaling file system" ... press on "down mark" you will see
11th option & from bottom 2nd option "SWAP AREA" .. just press on it.
Give 2 times your RAM size .... I have 4 GB ,so I gave 8192MB to "SWAP AREA".
8)After giving SWAP AREA ... allocate remaining space to
"/"(This is called root).
9) Press "Install Now" button.
After full installation .. reboot & you will see GRUB with ubuntu, ubuntu recovery mode, Windows 7...
Enjoy 😀
