The partition table written by Gparted:
The partition table written by BootFlash:
The problem is, we can see, the track size of BootFlash is shorter than Gparted....

Thanks smokey for testing. The problem comes from the incompatibility of the partition tables between 'BootFlash' and the Grub4Dosconfig v1.6.x. I will check the partition table in next version of grub4dosconfig. _________________ Multilingual Wary-511 Lucid Puppy Quickset edition Downloads for Puppy Linux http://shino.pos.to/linux/downloads.html |

Stripe, what I found really interesting is I did not need to check the boot flag with Gparted. _________________ Puppy Software <-> Distros <-> Puppy Linux Tips |

Shinobar, somebody commented on Barry's blog about their Windows install being broken after installing Grub4dos: http://bkhome.org/blog/?viewDetailed=01986 I'm not sure what went wrong. Maybe the "wee" boot code is too large and overwrote something important? Or maybe there is just something wrong with the code I gave you? (I never tested it with Windows) I think it might be a good idea to go back to the old method, using Grub legacy to chainboot Grub4dos from ext4

Shinobar and piratesmack , This is exactly??? what I experienced and luckily asked you Shinobar while that guy asked Barry instead . http://bkhome.org/blog/?viewDetailed=01986
And by your help I could get it to load the right code instead of the recovery. Unfortunately for him maybe him being too fast on the trigger going along with recovery changed the links to the older install of Windows. So could be tricky to find a way back now. Shinobar you gave me a better menu.lst code that actually changed to another partition so it loaded the right windows partition but I had forgot the password so I don't know if windows really works But it did look okay as far as it allowed me to go having now password to log in. _________________ I'm a noob so I use Google Search of Puppy Forum Last edited by nooby on Mon 22 Nov 2010, 18:12; edited 1 time in total |

My ATA CFD CSSD-SM64NJ2 has 19 sectors/track! (But no problem found with the grub4dosconfig v1.6.x.)
EDIT: Mybe i got it 
My ATA CFD CSSD-SM64NJ2 has 19 sectors/track, but the start point of the first partition is at 0x800(LBA), 2048 in decimal, means having enough space for the boot loader. But the BootFlash makes 32 sectors/track, and the start point of the first partition is at 0x20(LBA), 32 in decimal, means having less space for the large boot loader. We can see the start point of the first partition examining the 3 bytes, 0x1c6-0x1c8, in the MBR. I think the structure the BootFlash makes is breaking the usual rule. _________________ Multilingual Wary-511 Lucid Puppy Quickset edition Downloads for Puppy Linux http://shino.pos.to/linux/downloads.html Last edited by shinobar on Tue 23 Nov 2010, 04:08; edited 3 times in total |

Shinobar here is how it looks on my Acer D250 with Win7Starter it has wubi for Ubuntu on it but not sure if that shows up. # fdisk -l /dev/sda Disk /dev/sda: 250.0 GB, 250059350016 bytes 255 heads, 63 sectors/track, 30401 cylinders Units = cylinders of 16065 * 512 = 8225280 bytes Device Boot Start End Blocks Id System /dev/sda1 1 1567 12586896 27 Unknown /dev/sda2 * 1568 1580 104422+ 7 HPFS/NTFS /dev/sda3 1581 30402 231506210 7 HPFS/NTFS # menu.lst ended up on Sda1 but should be on Sda3 where all Linux stuff is on. Sda1 or Sda2 has the recovery thing on it. I guess that is how it is for the guy that if failed for too writing on Barry's blog. So if he did same change in the menu.lst that you told me than most likely he would boot windows correctly unless his recovery thing he did messed it up _________________ I'm a noob so I use Google Search of Puppy Forum |

Thanks for your PC's information. Humm.. the first partition (Unknown) is questionable. Can you see inside sda1 from Puppy? Will you show me the result of probepart?
I guess:

Sorry delay have to go buy food. 
# probepart /dev/sda1|ntfs|25173792 /dev/sda2|ntfs|208844 /dev/sda3|ntfs|463012420 # Sda1 have acerboot boot systemvolumeinformation factory sources and it have mbr and your mbr backup sda_mbr.bak and menu.lst Sda2 have boot systemvolumeinformation bootmgr Sda3 has all the rest. windows and puppy and most likely is seen as root. So the boot mbr backup and menu.lst seems to have ended up in the recovery partition? Unless sda2 is something else? _________________ I'm a noob so I use Google Search of Puppy Forum |

What i guessed.
Maybe no problem the grldr, menu.lst and sda_mbr.bak on sda1 when Puppy can access them. The problem was the boot menu mislead to the recovery windows on sda1 instead of the usual Windows boot from sda2. It is fixed with grub4dosconfig v1.6.1 and later. Thanks. _________________ Multilingual Wary-511 Lucid Puppy Quickset edition Downloads for Puppy Linux http://shino.pos.to/linux/downloads.html |

So what do you suggest the poor fellow that complained to Barry should do. As I get it he had same problem like I had only that he actually used the recovery not being aware of that one needed to change the menu.lst like you told me to. _________________ I'm a noob so I use Google Search of Puppy Forum |
