Making a bootable USB flash drive from PC

My DVD drive on Imac is broken and won't recognize anything. It doesn't show up on disk utility and I can't make dmg file from it.
So I have snow leopard DVD and I want to make a bootable USB flash drive on PC. I want to know how to copy the image from snow leopard dvd on PC. (windows xp)
Please help!

AFAIK, you can't use a PC. Consider one of these:

Mount a USB flash drive from a shell

I am about six months new to Linux; I have installed my first arch system but not yet installed a desktop environment. I am trying to mount a USB flash drive from the shell but I am not having much luck. I have tried following the instructions in the archwiki, http://wiki.archlinux.org/index.php/USB_Storage_Devices. I am having a problem with the following command:
mount -t vfat /dev/sda1 /mnt/usbstick
I get an error message saying that the mount point does not exist. I have in the /mnt directory the following:
cd cdrom dvd fd0 f1
(I am not sure what fd0 and fl are, if somebody could please tell me I would appreciate it. Also I do not have a DVD-ROM on my computer is the dvd listed by default or do I have a package installed I do not need?) I did some searching online and came across the following site, http://linuxcommando.blogspot.com/2007/ … -from.html. I followed the instructions to identify the correct partition name corresponding to the USB drive by running the following command:
grep SCSI /var/log/messages.log
and I get the following results:
Dec 30 22:16:17 morgan-desktop scsi2 : SCSI emulation for USB Mass Storage divices
Dec 30 22:16:22 morgan-desktop sd 2:0:0:0: [sdb] Attached SCSI removable disk
The next steps in the instructions are to mount the partition to the existing mount point (directory) by using the following command.
mkdir -p /mnt/myusb
mount -t vfat -o rw,users /dev/sda1 /mnt/myusb
This is where I am having a problem, I do not understand the results and how to proceed to the next step, please help me.
One other small question what is the best command to shut down the computer as a normal user?
Thank you
Morgan Smith

Ok, Lots of different advice here, let's see if I can explain it all together, and clear up a few bits...
I'll try to explain why I'm saying what I am, it doesn't matter if you don't follow it all, commands are below.
You are on the right lines here, but a few things missing. Firstly, to mount the USB stick you are using the correct command, but the locations are a problem. The command is "mount -t type what/to/mount where/to/mount". You can find out more about the mount command with "mount --help" or "man mount"
You have correctly identified type as vfat - this means the pen is formated as FAT.
To find out what to mount, you can check /var/log/messages.log, the second command you posted searches trough that file and prints out lines including the phrase SCSI, and the result tells you that a usb storage device had been attached as sdb, so the correct device is /dev/sdb1. Storage devices are named sda sdb sdc etc in the order they are attached, and the numbers refer to the partitions on the disk.
You can mount it anywhere you want, as any existing directory, but the one you tried to use /mnt/usbstick doesn't exist, so create it, using mkdir.
The commands you need therefore are:
mkdir /mnt/usbstick
mount -t vfat /dev/sdb1 /mnt/usbstick
This will work as root. There is also, as byte said, a program called pmount (which you can get with pacman -S pmount) which works the same way for a standard user.
Finally, there are also a number of tools like HAL which can be used to automate the process.
As for shutting down, as has been said you must be root or in the power group, then you can use 'halt' 'poweroff' 'reboot' or 'shutdown'. All have slightly different effects, and poweroff is probably the easiest.
Hope this helps

How do you save PDF to a USB flash drive from iPad 2

How do you save PDF to a USB flash drive from iPad 2

You can't, the camera kit connection kit which has a USB connection only supports the copying of photos and videos to the Photos app, and doesn't support the copying of any content off the iPad - you will either need to go via your computer.

Is there a way to protect a USB flash drive from virus?

My daughter's school computer lab is seemingly infected with some PC virus but their school IT folks seem to be unable to clean them and with all the young kids using USB flash drives they brought these viruses home when they plug the flash drive into our home computer but luckily since we are using Mac at home and I have ClamXav installed it detected the virus immediately. So we are kind of safe but I am getting tired of removing this same virus every week using UNIX command in a terminal mode, as it's locked and can only removed using the sudo command (taught by some people). My questions are:
1. Is there any way to protect a USB flash drive from virus infection (it's a window PC virus)
2. is there a way or suggestion on how to stop these apart from dis-infecting the whole school computers? The problems are that these young kids are not aware of those viruses in their USB flash drives and their teachers are just too ignorant about it!
Thanks for any suggestions and help

I'd still invest in your case into Mac protection against passing along malware.
Take a look at Intego AV for one for the Mac and for dual-protection.
http://www.intego.com
Whatever you are finding is 'dormant' I assume, but that doesn't mean it can't become active or passed along either. And there are some 'man in the middle' spyware and malware, some which target online home banking (some people run their home banking from a virtual OS that is used for that purpose only, I always wished Mac OS X could be run in a VM mode as well).
The IT folks sound like they need... do their jobs properly and better.
I don't care how young they are, or the staff's ignorance. Time for education is now.
Download and install Microsoft Security Essentials in Windows and follow guidelines. And there are tons of FAQs, guidelines and articles on the subject.

Using bootable USB flash drive to partition internal HDD

I just got my B5400 with Windows 8 x64 and UEFI. I found out that you can't lower the size of the hard drive by a lot. I want to split my HDD into 250GB and 666GB, one for the OS and one for data obviously. Therefore I tried the tool windows offered me but it said that I couldn't make a smaller drive because system relevant data are working at the moment.
So after searching the web I found out, that I have to use a bootable USB flash drive with something like Gparted running, to partition the HDD without any errors. I formatted my USB drive to FAT32 and made it a bootable stick with a program offered on the official website of gparted. I eagerly wanted to use it and plugged it in. Still booting into Windows. So I went into UEFI and checked the settings. I disabled secure boot mode and made it that legacy comes first. Then I chose 'USB HDD flash drive' in the boot manager and exited saving changes. I started my laptop and hit enter to et to the boot manager, made sure to select my USB drive and then confirmed it. It booted into Windows. I don't even understand why it is that way. It is like everything is set up correctly, but still it's trolling me.
I would appreciate any help greatly. And to make clear, I don't want to burn a CD or DVD, I want it to be working with a USB drive.

Hello,
search the web for "yummi bootmanager", it's free and easy to use.
If you got OKR (OneKeyRecovery) on your device, it will not longer work with resized parititions.

Booting from hard disks 2TB - bootable USB flash drive GRUB (w/o OS)?

Hi,
I'm thinking about setting up a hardware supported RAID on a Debian-server (Proxmox) with lots of HDD-space. Therefore, my RAID-array will be >2TB, but I've read that the BIOS of the system will not be able to boot from such. Do you have a solution for this?
I was thinking about installing a bootable GRUB on an USB flash drive, which would then chainload the RAID's GRUB for booting. Is this even possible? I couldn't find any tutorial on how to create/boot only a (customizable) GRUB from the flash drive.
Another option would be to create multiple disks by the RAID-controller, but i'm not sure what happens with the chunks, if i would add another disk to the RAID to expand it.
A third solution, that came to my head, is simply installing Proxmox on a separate disk and detach it from the RAID. But in case of a disk failure, it would not be protected and i would rely on snapshot-backups - so i rather would not like to go with that solution.
Let me know what you think!

I don't know about the answers to your issues, as I have never tried any disks that large. But it would probably be wise not to mention that you are trying to do this on a non Arch system, as now I am pretty sure you will not recieve the help you desire.
I don't mean to say that I encourage you to try to dupe our community into helping you with your debian system by not mentioning it. But it seems pretty silly to come to the Arch threads looking for debian support, even if it is a universal (os independent) issue.

Booting from Win 7 bootable USB flash drive?

What I thought would be rather simple has turned really frustrating, I wanted to install Windows 7, on my iMac, on a different partition.
I don't have a retail DVD but I have the product key for activation. So I downloaded the ISO Image from Microsoft. First I burnt it into DVD-R and booted it. It ended up getting stuck on 0% in Expanding Files. Then I tried to 'burning' it into USB and make it bootable, but I could not boot the USB flash drive on the Mac. How can I boot it? (I used the Windows 7 USB DVD Download Tool)
Thanks

Hi, I have a late 2008 iMac with a new hard drive. How do I install Mountain Lion from my bootable USB flash drive.

How do I install Mountain Lion to a new hard drive without having the recovery partition on it.
I have the USB flash drive with software on it but when I switch my Mac on all I have is a white screen & a flashing question mark.
ATB,
Steve.

Did you use LionDiskMaker or DiskMaker X?
Boot the machine with the option key down until you see your bootable USB stick. Select the latter, and reboot.
When the installer boots up, you will first need to choose Utilities and Disk Utility. Select the target HD device name and then the partition tab. Select 1 partition, name it Macintosh HD. Format is Mac OS Extended, and option is GUID. Apply. Exit Disk Utility and return to the installer, which will now show your newly partitioned HD as available for install.
When OS X is installed and all updates applied, press shift+command+U and run disk utility again. Verify/repair permissions and verify the boot disk.

How to create bootable USB thumb drive from Lion on Mac Mini 2011?

Hello folks
Yesterday my new Mac Mini (Core i7 2,7 Ghz, 4 GB RAM, ATI Radeon HD6630M 256 MB) arrived. It replaces my old Mac Mini (Core Duo 1,83 Ghz, 2 GB RAM, Intel GMA950 64 MB). One day I'll replace the 500 GB 5400 RPM HDD in this Mini by an Intel SSD drive (just like I did with my previous Mini). I'll do a fully clean install then (formatting the SSD drive in Disk Utility and then installing Lion on it from a bootable USB thumb drive). The only problem is I can't seem to download Lion for free from the Mac AppStore (MAS) although I have bought a new Mac Mini which came with Lion pre-installed. I know how to create a bootable USB thumb drive with Lion on it when you download it from the MAS. But that's the problem... I can't seem to download Lion from the MAS for free. When I open the MAS while holding down the Option key I can download Lion but it will charge me for it. Is there any way I can download Lion from the MAS without paying for it? Since it already came with my new Mac Mini 2011 this should be possible I guess?
And will I still be able to download the iLife '11 apps (iPhoto, iMovie and Garageband) for FREE that came with my new Mac Mini when I do a fully clean install as described above? Thanks in advance.
Greetings
Jocau

After doing some research, it seems that there are only 2 WAYS to do a complete reinstall of Lion on the Mac Mini 2011 without paying for the Lion download in the Mac AppStore (i.e. recreating every partition, also the Recovery HD partition, from scratch e.g. when installing Lion on a clean HDD/SSD).
1) COMPLETELY clone the Mac Mini 2011 HDD including all of its partitions to an external drive and restore it when you want to do a complete reinstall.
2) Use the LION INTERNET RECOVERY feature built-in into new Macs that ship with Lion (this feature is present in new Macs starting from the Mac Mini 2011 and Macbook Air 2011).
OS X Lion: About Lion Recovery
Lion Internet Recovery
If you happen to encounter a situation in which you cannot start from the Recovery HD, such as your hard drive stopped responding or you installed a new hard drive without Mac OS X installed, new Mac models introduced after public availability of OS X Lion automatically use the Lion Internet Recovery feature if the Recovery HD (Command-R method above) doesn't work. Lion Internet Recovery lets you start your Mac directly from Apple's Servers. The system runs a quick test of your memory and hard drive to ensure there are no hardware issues.
Lion Internet Recovery presents a limited interface at first, with only the ability to select your preferred Wi-Fi network and, if needed, enter the WPA passphrase. Next, Lion Internet Recovery will download and start from a Recovery HD image. From there, you are offered all the same utilities and functions described above.
As with the Recovery HD, reinstallation of OS X Lion from Lion Internet Recovery requires an Internet connection. See "Supported network configurations and protocols" below.
Restoring iLife applications after Internet Restore of OS X Lion
If you reinstall Lion on a new Mac that shipped with OS X Lion installed, on an erased or replaced hard drive, you can download iPhoto, iMovie, and GarageBand from the Mac App Store.
After installation, start from Lion.
Double-click the App Store icon in the dock.
Enter your Apple ID and password.
Click Purchases.
If you haven't previously accepted your bundled iLife applications within the Mac App Store, you should see your iLife applications appear in the Accept portion of the screen. Click Accept.
You may be asked for your Apple ID and password once again. Your iLife applications now move to the Purchased section. These applications are part of the software that came with your Lion based computer. Your account will not be charged for them. Click Install to compete installation of your applications.

It's a bit sad that these seem to be the only 2 options. Lion Internet Recovery is the preferred one here since my monthly internet traffic limit isn't a problem (but my download speed is). This problem could have been easily solved by Apple by just checking the system specs or serial number when trying to download Lion from the Mac AppStore. By using one of the 2 options in my previous sentence the Mac AppStore could see that I have a new Mac Mini 2011 that ships with Lion which would give me the option to download Lion from the Mac AppStore for free and eventually create a bootable USB thumb drive of it.

How to delete recovery in volume D and transfer it to bootable USB flash drive.

I am trying to create a recovery for windows 7 pro on a USB flash drive. i tried looking for HP USB recovery utility on HP website but they say that i will require a USB 2.0 port whereas ELitebook only has 3.0 ports! Also cant find the utility anywhere for elitebook. The builtin Windows recovery manager only allows recovery creation on a Disc but ELitebook doesnt have a CD drive either and I prefer recovery creation on a flash. Also my laptop packaging states that my purchase comes with windows 8 pro license and media. however i didnt receive any DVD media for that matter. Could Windows 8 setup files be residing within the recovery volume D ?\ any help in this matter will be appreciated.. regards, Sami Bangash

USB 3.0 ports are USB 2.x (and 1.x) backward compatible. Each USB version has different power specs, so while a USB 2.0 device will work fine in a USB 3.0 port, the opposite is not true. The Windows "media" is typically a compressed file stored in a Recovery partition on the hard drive. HP Backup Manager can be used to create a DVD (or set of CDs, whichever it uses) from the compressed file -- and that media can then be used to restore the PC.

How do I safely remove my sd card and usb flash drives from my iMac?

iMac newbie here. After years of PC messes and crashes I finally converted to iMac. However it's not always easy to find what I am looking for. The first time I disconnected a usb flash drive a warning appeared on the screen. I neglected to jot down the instructions. Now I want to remove the SD card for my phone, and I don't want to mess anything up. Can someone point me in the right direction? Thanks.

You posted in the iMac forum; to properly dismount any external drive from a Mac, drag its' icon to the trash can. Then you can unplug it. I don't have an iphone, so I can't answer that. You'd get more knowledgeable answers for that question in an iPhone forum.

[Help] How to wireless transfer data to an USB flash drive from an iPad mini 2

Hi.
I want to use my iPad for my exams, but I'm not allowed to use the internet to send my files under the exams, so I need an alternative way to do it. I want to copy pages, numbers and keynote files to a wireless USB flash drive when I'm done. Do you know a product that can do it, that is also available in the Amazon UK?
Thanks.

Hi Loner,
Thanks for the reply.
I have located the program and will give it a try.
Cheers.

Unmounting USB flash drive from cRIO

Hi all,
I am using the USB port of a cRIO 9012 to save datafiles (using File I/O) to a USB flash drive.
After having run the program, I want to unmount the USB drive. Can anyone please tell me if there is a better/nicer way than just taking it out? Since this might result into losing my data if the USB drive gets corrupt (just like under Windows).
I have searched the forums, but I was not able to find anything on dismounting a USB drive on a cRIO...
Hopefully you can help me solving this (little) problem.
Thanks in advance,
Joep

Joep,
under Windows there are two scenarios that could cause data corruption on a USB-Flash-Drive:
The Flash-Drive is removed during a write operation. This potentially destroys the FAT which results in data loss. There is not much that you can do against this behavior, neither on Windows, nor under VxWorks.
With caching enabled for the Flash-Drive there is a chance that files are not written to the drive completely because some parts of it are still sitting in the PC's memory. When the drive gets removed the data is corrupt.
I don't think that VxWorks uses cache for mass storage devices at all so this issue shouldn't be relevant for a cRIO-9012, but I will double check if this is true.
Best regards,

Snow Leopard Bootable USB Flash Drive with Lion

I'd like to create a bootable Snow Leopard Flash Drive, after upgrading to Lion. I have multiple Macs with some expensive legacy software and an Apple USB modem (32 bit) I use out in rural areas. I'm assuming this will be a viable solution - is there something I'm overlooking? Has anyone else out there taken this route?
Thank you.

That would have to be a fairly large flash drive in order to install OS X and any PPC aps on it. You'd be much better off installing Snow Leopard on a separate partition on your internal HDD or an external one. (Since you have multiple macs, installing on an external HDD seems to be best.

Install Arch in an USB Flash drive from an existing image

I want to minimize the amount of writes to the flash drive by avoiding directly installing Arch into it.
I would like to know if it would be possible to install arch into an small partition, configure it, and then make an image of it and dump it at the USB drive(like when creating the USB install).
Does it worth the while doing so?
Thanks!

Sure. You could do that, then just rsync or cp -ax it onto the Flash drive and set up GRUB.
