Intall syetem using DMG

2010-10-13 Thread Gottick International

Folks,

I'm trying to install X5 on a machine that won't accept the newer,
larger, DVDs. I have moved a X.5 .dmg to the computer's hd and now I'm
trying to reboot the whole machine from the dmg. Is that even  
possible? Iv'e been told so.

No such thing as a machine that won't accept the newer, larger,  
DVDs. I assume you're talking about dual-layer DVDs? ALL DVD units,  
whether they're Combo, DVD-ROM, or DVD-RW support dual-layer read. I'm  
assuming by X5 you mean Leopard 10.5, the first OS to ship on dual- 
layer discs. The only reason your optical unit wouldn't work with a  
dual-layer DVD is if you only have a CD-ROM unit instead of a DVD  
unit. This applies only to commercially produced dual-layer DVDs, if  
you happen to have a home burned copy on a dual-layer DVD-R or DVD+R  
disc, this could possibly not work, and often firmware updates for the  
DVD drive can add support for more media types and enable an  
unreadable disc to work, BUT you probably need a Windows PC in order  
to update the firmware.

No, you can't boot from the .dmg file. You must clone the .dmg onto a  
partition and then boot that partition. You can't clone onto the  
entire HD and then install onto the same HD; you'd need either two  
separate partitions or two separate drives. You may be able to clone  
onto a USB flash drive and then boot the USB drive to install, but  
first you'd need to reformat the USB drive as HFS+ journalled with  
the appropriate partition map (Apple partition map for PPC Macs, GUID  
partition map for Intel Macs) using Disk Utility. You can clone  
the .dmg with Carbon Copy Cloner.

As Kris said, you cannot boot from the drive that you are going to 
install to. If you have a second Mac you can install to the first Mac 
using Firewire Target Disk Mode (connect the two Macs with a firewire 
cable, restart the 'target' mac holding down the 'T' key, as soon as the 
Mac's hard drive shows up in the other Mac's Finder sidebar as an 
external drive you can install).


It sounds convoluted but it really isn't.

Yupp

Probably what is happening here. Oddly enough some burned DVDs are  
accepted and some are not.

No, you can't boot from the .dmg file. You must clone the .dmg onto  
a partition and then boot that partition.


Can it be done from an external HD?
