How do I place a bootable ISO on a USB drive?

What's the best way of placing a bootable ISO on a USB drive, such that the drive is bootable? ISOs such as a live Linux preview disk, Windows installation ISO, etc.

How do you protect your computer from Live CD's?

Linux has grown in popularity in the past few years. Many more people are using Live CD's now than they were say 3 years ago. And with this comes a new problem for network admins. How do you stop a person from accessing certain file on the HDD that they, under Windows, would not be allowed to access, or even see. If you have a personal computer you can't really protect it either. A password on the BIOS won't work because if you remove the battery on the motherboard, wait 10 seconds, insert the battery back in, your password is gone.

How do I stop this threat?

CentOS Live CD vs Live DVD download

In this download page, I am presented with some options: http://mirrors.arpnetworks.com/CentOS/6/isos/i386/

What's the difference between Live CD vs Live DVD?

  • CentOS-6.3-i386-LiveCD.iso 690M
  • CentOS-6.3-i386-LiveDVD.iso 1.6G

Don't they just contain the same data? Why would I want to download Live DVD if Live CD is significantly smaller?

Is there a difference between an Ubuntu Live CD and an Ubuntu Install CD

I ordered for an Ubuntu Install CD and obtained a CD by post (Ubuntu 9.10). Is this a Live CD or an Install CD ? What exactly is the definition of a live CD ?

Are live CD/DVDs more secure than live USB?

If you create a bootable live CD/DVD for an OS such as Linux or Windows, is that more secure than a live USB that does the same thing? What if the disk is a CD-R or DVD-R as opposed to a CD-RW or DVD-RW? What I am interested in is malware in-place modifying the media on which the live OS is stored, and possibly infecting machines on which the live disk or USB is inserted into and booted from.

Get last successful boot time from a Windows hard drive

I work for a company that has installers go into people's homes and set up their internet connection. In the past 2 weeks we have had a customer say that we broke their computer. Our installers aren't smart enough to see that they have a problem, stop, and inform the customer immediately.

What I'd like to do is set up a small live Linux CD that will mount all drives on the computer as read only and read the log files for the latest date that the computer was successfully booted, and if possible, connected to the internet. Any ideas as to which log files I might look at for the last successful boot on a Windows 2000, XP, Vista, and 7 machine?

Which Live CD Linux distros have Chrome preinstalled [closed]

Which Linux distros that have live CD (or live USB) come with Chrome browser preinstalled ?

If you mention distros that do NOT have Chrome preinstalled,
it also helps :-). Because it narrows the search.

Tried Linux Mint 11; no Chrome.

Thanks

Live Linux CD for burn-in with Bonnie++?

Is there a live linux distro that I can use for burn-in? I'd like something that has Bonnie++ on it. I've found other live CDs that have utilities, but nothing with bonnie++ on it.

Linux Live CD for old computer

I have a pentium II (that's right, pentium II) with a scant 200MB of ram. This was a high-end workstation in it's day. The machine currently runs dos on a raid array, and I need to pull some data from it. I figure my best chance at this is to use a linux live cd to copy the data to one of our active directory network shares (there is a network card in the machine).

Unfortunately, my linux skills are abysmal, so I'm not sure where to get started:

  • Where should I look to find a linux cd that will run well on such an old system
  • Since I'm likely gonna need to be command-line only, what do I need to do to configure the network card and mount the network share via the command line?
  • Bonus points: exact syntax needed to copy and convert the entire volume for use in VMware server 2.0, but really just copying all the data should be enough.

Access boot menu from Windows 8 PC

I have a computer that came with Windows 8 preinstalled. I want to boot from a CD, in this case Hiren's Boot CD. However Windows 8 doesn't seem to like this.

I have tried pressing F8, ESC, F12 and so on. I read online that Windows 8 can boot in 200ms, so that it might not even be possible to boot from a Live CD before Windows loads.

I would like to know how to boot from a CD before Windows loads, if possible. If not possible, how to boot from the Live CD after Windows loads.

After further tinkering I was able to get to the BIOS using F2. I changed the settings to boot from CD first, and I even disabled "Secure Boot". The computer seems to ignore these settings and booted Windows anyway. I was also able to access the "Boot Menu" using F12.

I choose "CD drive". It did a "media check" on the CD even though I disabled Secure Boot, and the check failed; again it booted Windows after that!

Fastest booting Linux ditribution on a live-cd

I'm looking for a linux distro with the following:

  • Boots quickly, as fast as possible.
  • Has expected tools such as file browser, a web browser, etc.
  • Doesn't need to have extraneous recovery stuff such as partition editors, and what not.

These are the tools I have and use already:

  • ophcrack
  • Ultimate Boot CD for Windows (UBCD4Win)
  • chntpw (Offline NT Password and Registry Editor)
  • Hiren's BootCD
  • gparted or Parted Magic
  • Ubuntu
  • nubuntu

Any and all suggestions are welcome :-) The primary objective is to get a quick booting linux distro that I can grab / delete / move / copy files with.

Currently, I prefer using ophcrack, it boots in (relatively) fast and I can manipulate files well. The one that takes the longest is ubuntu of course.

How do you create a bootable partition on a USB drive?

I have a bootable ISO designed to be burned to a double-layer DVD. I don't have a double layer DVD burner, so I would like to stick the ISO image on a 50 GB partition on a USB hard drive I have. How do I get the boot info onto the hard drive?

Attempt 1:

  1. booted into Ubuntu 9.04 LiveCD
  2. deleted the partition on my existing USB hard drive
  3. sudo dd if=/path/to/image.iso of=/dev/MyUSB
  4. booted to USB drive
  5. error: Error Loading OS

Atempt 2:

  1. booted into Ubuntu 9.04 LiveCD
  2. deleted the partition on my existing USB hard drive
  3. sudo mkdosfs -I -v -n iPC /dev/MyUSB
  4. sudo syslinux /dev/MyUSB
  5. sudo dd if=/path/to/image.iso of=/dev/MyUSB
  6. booted to USB drive
  7. error: Selected boot device not available - strike F1 to retry boot, F2 for setup utility

How can I restore GRUB without a live CD?

I realize that this is a duplicate of a question asked before, but in that question the asker managed to find his live CD and no real answer appeared, thus I am re-asking it.

I managed to screw up my GRUB by deleting two linux partitions on my hard drive from windows. After this, GRUB gives the error "partition not found", and gives me the grub-rescue> prompt. The only command I have found to work in this is 'ls', which spits out my partitions. I would use the live CD fix, but I am in India, and all my live CDs are back home in the US... What I've got is an internet connection, a 4GB flash drive with Flow OS installed (which I am currently using but can wipe if need be), and a working laptop that I can borrow. What should I do?

Booting an Asus EeePC from a LiveCD USB stick

I have two identical Asus EeePC netbooks that are both installed with Ubuntu. One of them was sitting on the closet shelf and the battery went completely dead. When I charged the battery and tried to boot the it, I got the "No init found" error. In trying to follow the suggested way to fix it posted here, I used the Startup Disk Creator on my Ubuntu 11.10 desktop machine to create a USB stick with a bootable Ubuntu 11.10 live CD on it (the netbook doesn't have a CD drive).

I plugged the USB stick into the netbook with the init issues, went into the BIOS and selected the USB stick as the 1st choice to boot from, and did a hard restart. It then just stuck at the flashing underscore. Not knowing why it wasn't working, I tried booting my working netbook from the USB stick. When I got into the BIOS on the working netbook, I noticed the description in the boot order section for the USB device was different.

On the non-working netbook, the description was SWISSBIT (the name of the USB stick) but on the working netbook it was just "Rem. Drive". I also noticed on the working netbook there was an additional option under the bootable order section that allowed me to choose which hard drive to boot from. This section showed two hard drives, one of them being my USB stick. So, rather than changing the device boot order, I selected the USB stick as the hard drive to boot from first and it worked like a champ - I was able to boot into the LiveCD on the USB stick.

Seems to me the working netbook is seeing the LiveCD USB stick as a hard drive, where-as the non-working netbook is seeing it as a plain ol' USB stick. The BIOS is the exact same version on both netbooks... any idea why it works on one and not on the other?
