installed kubuntu 13.04 but it did not shows up

[Sultan101]

hi

i have installed successfully kubuntu-13.04-desktop-amd64 and at the end i pressed restart now as it says then black screen asked me to remove the disc then press enter but at this point the system freezes and nothing happened.

so i had to press the restart button but the system goes directly to windows 7 and did not recognize kubuntu

what should i do ??

------
i have windows 7 x64 on c drive
16gb ram
1TB hdd ( 400gb c drive + 80gb kubuntu )
MB: GA-Z77X-D3H gigabyte
-------
P.S.
i have installed kubuntu and ubuntu on my old pc desktop with xp pro 2 years ago no problems

Does GRUB even come up or does it go straight to Windows?
Boot repair might be the answer if so.

[Sultan101]

system goes straight to windows 7 as if kubuntu never existing.

please then tell me how to do a boot repair in few and specific steps?

Check the boot repair thread in the Installation and Upgrades subforum. It has more info than I could ever give you (especially since I've never had to use it...yet.)

[Sultan101]

i have read some threads there and got panic

i am not an expert since it did not work out of the box then i am going to delete the 2 partitions (kubuntu + the swap are ) and forget all about linux

but will this affects windows anyhow?

---------------------------------------- update ---------------

i just delete the 2 linux partitions and joined them to c drive (thank god no problems at all )

cincinnatus13 thak you for quick replies

With Windows 7 (assuming you don't have a UEFI BIOS), there shouldn't be much of an issue with installing Kubuntu.

I would recommend trying again but first, check the MD5 of the ISO before putting it on a USB/CD. Then check it for defects before installing.
If you need help, post back.

this is my MB : GA-Z77X-D3H gigabyte and and it has a UEFI Bois.

I did little search on UEFI and linux to find out that the reason of linux not booting is the UEFI.

right now the only linux distributions support the UEFI are : Fedora 18 , Ubuntu 12.10 and OpenSuse

i hope you verify my info

First try boot repair.
Follow the instructions, there very straight forward.
Option #2 works best, IMHO.

And second, I think you're confusing UEFI with secure boot.
Look over oldfred's UEFI installing tips tutorial for more on the issue
