 Posted: Wed Jun 27, 2007 1:02 pm Post subject: (install) boot .iso |
 |
|
I would like to propose an official new alternative method to install gentoo. This method allows you to boot the downloaded .iso directly from your ntfs/fat partition.
Advantages:
- no cd-rom player needed (some laptops/tablets)
- no cd-rom wasted 
- upgrade is as easy as overwrite your .iso (in case when one uses livecd only)
- add files to your iso as you go, without having to reburn (preadd depencies/drivers etc) with PowerISO
What you'll need:
- Windows NT/2000/XP/2003/Vista
- any bootable ISO archive
Nuf said here's what to do:
Step1:
Download IsoEmu 109th or visit here.
Step2:
Open the archive and extract these two files:
- ieldr (not ieldr.exe) to your c:\
- isoemu.ini to the root of any partition (that later will be containing your iso), e.g. c:\ or d:\
Step3:
Copy your ISO to the same location as isoemu.ini and then edit isoemu.ini and delete all text inside and add
isoemu.ini:
Note1: gentoo.iso should correspond to the name of your ISO archive.
Note2: IsoEmu is limited to filenames of maximum 8 characters and 3 for the extension (8.3 format).
The next step differs for Vista from NT/2000/XP/2003. We'll first discuss the latter here first.
Step4a:NT/2000/XP/2003
Go to c:\ and edit boot.ini and add the folowing data at the bottom of the file:
boot.ini:
| Code: | | c:\ieldr="IsoEmu Loader" |
You can edit the line containing timeout from 30 to 5 seconds.
Note: if you can't find boot.ini; turn off "Hide Protected Operating System Files (Recommended)" under Tools/Folder Options>View in any folder.
Step4b:Vista
Goto start, type in cmd.exe, rightclick your result, choose "Run as Administrator", accept all warning yadayada. Type in the following code:
Administrator: Command Prompt:
| Code: | bcdedit /create /d "IsoEmu Loader" /application osloader
bcdedit /set {id} device boot
bcdedit /set {id} path \ieldr
bcdedit /displayorder {id} /addlast
bcdedit /timeout 5 (optional: sets time-out to 5 seconds) |
Note1: the first command will return an id similair to {520fccd5-248f-11dc-87a7-000000000000} this you'll need to copy (rightclick>mark>select>rightclick) and paste everytim istead of {id}.
Note2: bcdedit /enum will give you the current entries in the list.
Step4c:Grub
With use of Grub4Dos (which offers chainloader and is recommended over Grub (dos edition)) you may edit menu.lst and add at bottom:
menu.lst:
| Code: | title IsoEmu Loader
find --set-root /ieldr
chainloader /ieldr |
Fin!
Ofcourse this method can be used to boot anything like Knoppix, WinPE, Ultimate Boot CD etc. |

power iso doesn't work for me. I use magiciso to create iso file instead.

| You can use any software that can edit the iso files. |

boot.ini:
Code:
c:\ieldr="IsoEmu Loader"
added it to the bottom of my boot.ini
When I boot, there is XP, XP64, and isoemu, when I hit iso emo it shows the isoemu for like 2 seconds and at the bottom it says NTLDR is not found or something
| Code: | [boot loader]
timeout=10
default=multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0
[operating systems]
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS.0="Microsoft Windows XP Professional" /noexecute=optin /fastdetect
multi(0)disk(0)rdisk(0)partition(1)\WINDOWS="Windows XP Professional x64 Edition" /noexecute=optin /fastdetect
c:\ieldr="IsoEmu Loader"

its is not necessary.
You have both the windows installed in one partition. Maybe thats the problem.
Anyway that thing should not be a problem if you use the grub4dos method. |

No you have to either install the grub4dos as the boot manager or use the grub.exe file in its package to start it.
Check the grub4dos tutorial at its wiki here

Did you edit isoemu.ini and put the correct name for the iso file there?
Did you put the ISO file in C:\ |

First as you are trying to boot a windows disk you were supposed to post the problem in off the wall section.
Secondly Windows doesn't support creating live cds except through specialized software like BART PE |
