    Burning a bootable disk


    I am trying to burn a bootable disk from a Windows 7 ISO for my brother he had lost the original media OEM I gave him with the machine I upgraded the CPU and RAM SSD etc for him..

    Now I have done this before using PowerISO and did that at a relatively slow rate because I am under the impression that the burn rate should be max 4x and better if slower to prevent files corruption. Now the lowest speed I can find with PowerISO tonight is 8x (or max) so has anyone got n=any suggestions for another burner so I can burn at a slower rate or is it ok to burn at high rates as I am not sure now.

    Why not just do it to a flash drive using rufus or similar?

    The optimal burning speed is determined by a combination of factors; including the type of dye used on the blank disc, the manufacturing quality and QC, the list of burning strategies codified in the firmware of your DVD burner, the condition of the laser, and the stability of the spindle motor that spins the disc.

    The "burn at 4X" is something of an old wives tale which ignores most of the above in a blind attempt to keep to "slower is better". This isn't always true; many drive transports have significant jitter when spinning at the lowest speeds which impacts on readability. I personally use "one speed lower than the maximum useable speed reported back to the burning program" as my guide.

    Also, if a decent burning program consistently gives you a choice of only ONE burning speed with a particular drive/disc lot, it may be because the disc's dye type (MID as read from the pregroove) is unknown to the drive's firmware. In that case the DVD burner is using "failsafe" mode for speed and strategy selection; which may or may not give you such great results. If that happens, I'd sooner try a different type of blank than looking for another burner. After you do the burn, run a verify pass on the ISO vs. burned CD to be sure it's OK.

    Or, as a previous posted has suggested ... create a bootable USB install drive instead.

    I haven't worried about burn speeds in years. Most software seems to have an "automatic" setting, so I just use that. No issues anymore.

    Your line of thinking was correct back when we all had slow IDE spinners and IDE burners on the same channel.

    Ok well I have got the general consensus I might send him sticks as well as DVD's my gear is fairly new the Sandy running a good Liteon and the Ivy runs a Blu ray and bot the Asus lappies have Matsusushitas.

    It is just that I am not fan of sticks to be honest but will send him disks and them. I only am concerned because of him being in the UK and I the machine I did him up is now getting on though he could do it himself I just wanted to do something for him plus I am sending him some spare SSD's I have - he has had some terrible luck just lately.

    I do however tend to agree that the media should be quality branded stuff though, and it will be interesting if I send ISO's from the 7 and 10 machines.

    Thanks for the advice.

    This one never fails me.

    Free ISO Burner

    I also use Power Iso which is my 1st choice.

    But if 8x speed is the lowest you can use, give it a go I think it should work.

    If there`s an option to verify after the burn then use it.

    Hi there

    If using USB sticks (IMO far more robust than Optical media) simply create a bootable drive by using RUFUS and the iso image from a HDD.

    I usually do that -- from the Windows media creator tool I stop at the ISO stage (i.e I just create the ISO) and then make a bootable USB stick with the rufus program --works every time.


    Rufus - Create bootable USB drives the easy way

    Also if posting from 'OZ to GB you are much less likely to get damage, loss etc -- + it's easier to package for postage.

    Cheers

    Problem with rufus is it is easy to get it wrong especially for a uefi install.

    I use the diskpart method that always works

    Open admin command prompt and type:

    diskpart
    list disk
    select disk n (n = usb drive)
    clean
    create partition primary
    select partition 1
    format fs=fat32 quick
    assign
    exit
    exit

    You can create a text file with above eg usbsetup.txt and run it simply with

    diskpart /s usbsetup.txt

    Note: This assumes you always know the usb drive number - if you had other usb drives attached, you would need to check first and edit file.

    Then mount iso as a drive and simply copy all files to usb drive.

    This method always works on uefi or bios installs.

    Look I keep losing posts as the forum page keeps logging me out so I will keep it short.
    Brian I will try your suggestion out over the weekend and Jimbo haven’t heard for my brother yet so don't know if he would be happier with a stick or disk but if I send both I can kill the bird with two stones eh??

    To be honest I thought all DVD's were made using a universal manufacturing standard although I always use well known brands but have found Maxell disks burn faster even at the same speed as when using Philips brand ones using ImgBurn at 2.5x even though it offered 1x as the slowest speed.
    So I will test a couple out over the weekend and see what the go is using whatever method to test the burnt disks.
