11.10boot failure
I've already installed ubuntu 11.10 64bit version on my PC, but it won`t boot into ubuntu.
i only get black screen then system suddenly reboot and then i only got blank flickering screen
i`ve already tried installed it without downloading update and third party software, but i still got the same result
my partitions for ubuntu are :
4gb /swap
,12gb /
,8gb /home
my PC spec :
unlocked phenom X4 b45 ,
Ati radeon HD 6850,
4 gb of ram
Try the option of "nomodeset"
The newest kernels have moved the video mode setting into the kernel. So all the programming of the hardware specific clock rates and registers on the video card happen in the kernel rather than in the X driver when the X server starts.. This makes it possible to have high resolution nice looking splash (boot) screens and flicker free transitions from boot splash to login screen. Unfortunately, on some cards this doesnt work properly and you end up with a black screen. Adding the nomodeset parameter instructs the kernel to not load video drivers and use BIOS modes instead until X is loaded.
Press any key at that moment to access a menu. Select your language with the arrow keys, press enter and you will see this menu: Then select F6
I had a similar situation with my Asus U46E. Try the following see if it helps (it worked in my case):
Right after selecting English in GRUB, hit F6, it will bring up a list of GRUP boot options. I checked nolapic and then it booted fine.

I had the same issue. It has to do with your graphics card. On your grub page, you can boot using "nomodeset" instead of the "no splash". This might help, although you can do it from grub as well (LiveCD not needed). That way you will get basic functionality so you can change your drivers.
My issue was resolved when I upgraded to 11.10, even though the ATI drivers were the same. I'm assuming Unity was fixed, so I suggest you work with the generic drivers for a time until Ubuntu releases more updates.
